Preparation of Phase – Pure Nanocrystalline Anatase and Rutile TiO2 using Hydrolysis of TiCl4 in presence of surfactants
Abstract: Hydrolysis of TiCl4 was carried out in two different ways to prepare nano crystalline TiO2. In the first method the hydrolysis of TiCl4 was carried under high acidic conditions at low temperature. In the second method hydrolysis was carried out using (NH4)2SO4 as an additive. It can be seen that the hydrolysis of TiCl4 under high acidic conditions promotes the growth of rutile phase of TiO2, where as hydrolysis in …

Review of Nitrite Inhibitor for Protection of Rebar Corrosion
Abstract: Load bearing concrete structures need steel reinforcement (rebar) strips or rods, which are prone to attack by the corrosive environment inside the concrete due to constant ingress of moisture, pollutant gases and anions (mainly Cl-, SO4- -). One of the means of reducing such type of corrosion is the use of inhibitors. Inhibitors are water soluble but film forming on metals by their selective adsorption on the metal surface. These …

Utilization of Agricultural Waste for Defluoridation of Water: A Review
Abstract: Fluoride is an essential micronutrient for human health which can be obtained from food items. Excess fluoride is one of the anionic, inorganic contaminants, found predominantly in ground water due to weathering of rocks, geochemical reactions or anthropogenic activity such as disposal of industrial wastewaters, because of which removal of excess fluoride is mandatory. Among various methods used for defluoridation of water, adsorption is widely used. It is more remarkable …
