The presence of fluoride in water meant for household and industrial purposes is very harmful as it can adversely affect the health of people drinking that water. Any amount of fluoride in drinking water can lead to diseases like fluorosis, which can lead to brittle bones and mottling of teeth. The presence of excess fluorine compounds in the body will prove harmful in the long run as it causes skeletal fluorosis. This condition can cause severe pain and damages to the bones and joints.

In order to prevent such conditions from taking place, it becomes absolutely necessary to remain the traces of fluoride from the source itself. The source, in this case, is the drinking water being supplied by municipal corporations. Hence municipal corporations around the world make use of different methods to remove all traces of fluoride from the water being supplied to households and industrial corporations.

The process of removing fluoride from water is known as defluoridation. Different methods are employed to bring down the levels of fluoride in the water so that it becomes fit for human consumption. While there are many methods of defluoridation, only those procedures are preferred, which not only remove the fluoride molecules, but also do not bring about any major changes in the quality of the water being supplied.

 Defluoridation Using Aluminium Oxide

Aluminum-OxideThere are many methods of ensuring safe fluoride levels in drinking as well as water meant for industrial purposes. Some of these include distillation, reverse osmosis, electrodialysis and resin de-unionization. However, these methods do not ensure that the water being supplied will be adversely affected by the treatment procedures.

This is where the method of using Aluminium Oxide for defluoridation becomes important. Aluminium oxide is a widely used desiccant, mainly used for defluoridation because of its even-sized pores and large surface area. Both these features ensure that more humidity/impurity molecules are absorbed over the much more area. Also Read: Best Guidelines for pharma packaging

Coming to Aluminium oxide, it is a chemical made by combining aluminium and oxygen with the formula Al2O3. Also, as alumina, aloxide, aloxite and alundum, Aluminium oxide is widely employed by many industries and companies for various purposes. Aluminium oxide is mostly found in its crystallinepolymorphic phase α-Al2O3. In other different combinations, aluminium oxide can also form precious gemstones like ruby and sapphire. Aluminium oxide also finds use in producing the aluminium metal, mainly because of its hardness. Not only its hardness, its high melting point helps it be used as a refractory material as well.

How Aluminium Oxide Works


Aluminium oxide or Activated Alumina, as it is commonly known, is mostly used in water treatment plants mainly because of its unique properties. These include a very high surface-area-to-weight ratio, i.e. more water molecules are absorbed over a large surface area. So with the help of Activated Alumina balls, more fluoride molecules will be absorbed over a larger area. As the water treatment procedure gets underway, more and more fluoride molecules will get attached to the activated alumina desiccant. In this manner, the water will get purified and almost all the fluoride and arsenic elements present in the water are successfully removed.

Another reason why Aluminium Oxide is most preferred for removing fluoride from drinking water is that it has numerous even-sized pores, which can adsorb the fluoride molecules in such a manner that they cannot move out. This feature goes a long way in ensuring that the fluoride molecules are effectively removed from the water and the latter is 100% fit for human consumption.

A point to be noted while using Aluminium Oxide is that the cartridge needs to be replaced from time to time as the absorbed fluoride will stick to it and over time the efficiency of the cartridge will be reduced.

Uses of Thin Layer Chromatography in Everyday Life

Thin Layer Chromatography – An Introduction

Thin layer chromatography is a simple and effective type of chromatography mainly used to separate and study individual components of any mixture. Thin layer chromatography or TLC, as it is commonly known as, is highly popular because it is inexpensive and can be completed within a short period of time. Out of the different chromatography methods available like analytical, flash, etc., thin layer chromatography is the most used as it can provide a quick and accurate segregation of the different constituents of the mixture.

Thin layer chromatography consists of a glass, metal or plastic sheet, on which the stationary phase like Silica Gel or Aluminium Oxide is placed. Then the mixture that has to be separated is kept at one end of the plate. In the next step, the thin layer chromatography plate is placed in the liquid phase, also known as the eluent. The TLC plate should be kept in such a manner that only its bottom end touches the liquid. After some time, the eluent will slowly move up the TLC plate by the means of capillary action.

As the eluent moves up, the molecules of the mixture will react with the contents of the solution and achieve equilibrium. Over a period of time, they will settle down in different layers according to the equilibrium achieved. The layer formation depends on the solubility of each component. While some may be adsorbed faster, some others will move to the farther end of the plate. As soon as the solvent reaches the top of the plate, the separated components are removed and taken for individual analysis.

Use of Thin Layer Chromatography in Routine Life

There are many uses of thin-layer chromatography in our daily lives. Some of these include:

1) In Food Industry: In the food industry, thin layer chromatography finds use in separating and studying various aspects of food items like their colours, sweetness, preservatives and other angles.

2) In Cosmetics Industry: The thin-layer chromatography method is widely used in the cosmetics industry to separate and analyze different cosmetic products and their components.

3) In Pharma Industry: Thin-layer chromatography is employed in the pharmaceutical industry to study different medicines like hypnotics, sedatives, anticonvulsant tranquilizers, antihistamines, analgesics, local anaesthetics and steroids.

4) In Biochemical Studies: TLC is widely used in biochemical analysis for the isolation and separation of biochemical metabolites or constituents from human body fluids, blood plasma, serum and urine.
