An Experimental Study of Spherical Agglomeration of Benzoic acid And Influence of Process Parameters
Abstract: Through the process of drowning-out crystallisation in three partly miscible solvent mixtures, sphere aggregates of benzoic crystal have been successfully created. The mixture of benzoic acid, isopropyl alcohol, and bridging liquid is supplied to an agitated crystallizer with water acting as the anti-solvent. When a substance crystallises, little crystals are formed, and the bridging liquid causes the crystals to group together. Different solvents are utilised because benzoic acid crystals wettably …

Catchment Pollution Potential and Pattern of Groundwater Quality
Abstract: Pollutants in groundwater can occur naturally or they can be introduced by various anthropogenic sources of pollution. Both point and non-point sources of pollution affect the quality of surface as well as ground water. As water infiltrates, solute concentrations are typically low. But after penetration their spatial extent follows a regional pattern that needs to be examined in detail. Hence, spatial pattern of important parameters of ground water quality obtained …

Bioremediation: Removal of Pb2+, Cr3+ and Cd2+ from Aqueous Solution using Immobilized Ficus sycomorus Leaves
Abstract: Abstract This study investigated the effectiveness of immobilized Ficus sycomorus leaves (IFSL) for the removal of Pb2+, Cr3+ and Cd2+ions from waste water. The immobilization of Ficus sycomorus leaves was achieved by entrapping it within a polymeric matrix of calcium alginate. Sorption capacity (in percentage) of IFSL was determined from the decrease in the concentration of aqueous solutions of Pb2+, Cr3+ and Cd2+ with reference to the final concentrations of …

Monitoring the Effectiveness of Water-Based Plants for the Inhibition of Metal
Abstract: The temperature performance profile of the plant extracts shows that inhibition efficiency increased with increasing temperature of the system until at about 323K at 9.00hrs immersion time where a decline in inhibition efficiency occurred implying the opposite at higher temperatures and longer immersion time. Corrosion rate parameters changed with rise in temperature and exposure – immersion time. Plots of rates of corrosion against the volume(s) of the test inhibitor(s) in …

Influence of Acidic Naf-Hf Solution on Dental Minerals
Abstract: The effect of solutions of sodium fluoride in hydrofluoric acid on the fluoride-dental minerals reaction system was investigated. The fluoride concentration in each fluoride solution was kept at 1.23% as the fluoride concentration in the acidulated phosphate fluoride solution at pH 3. The acidic sodium fluoride-hydrofluoric acid solutions with different contents of sodium fluoride and hydrofluoric acid were prepared. These solutions were added to synthetic powder hydroxyapatite and calcium hydrogen …
