Present study was undertaken to analyze and select most appropriate method for removal of fluorides in rural areas. Five methods were analyzed in details with mechanism and limitations.The methods are: Activated Alumina, Red Mud, Montmorillonite, Nalagonda Technique and Magnesia. The Study reveals that magnesia is the most appropriate fluoride treatment device for rural areas.

In the course of screening against Pellicularia sasakii, a fermentation broth of E327, a species of Streptomyces, was found to be effective against rice sheath blight disease. The active substances resembled the bleomycin group by thin-layer chromatography and were purified by methods reported for these antibiotics1}, using activated charcoal instead of alumina. Five antibiotics were separated ...

This report is an evaluation of the selenium removal from agricultural drainage water and synthetic solutions contaminated with high amounts of selenium. Batch and kinetic studies were conducted on the removal of selenium and the effectiveness of various remediation materials was determined. The agricultural drainage water samples were obtained from San Joaquin Valley and provided by Department...

Formaldehyde is extensively used for disinfection and antisepsis in medical facilities and especially in textile and paint industries as a solvent. Owing to the higher concentration of formaldehyde, both in waste effluents and local environment of medical facilities and industries, it has been reported to cause cancer and as an irritant to eyes and skin. The removal efficiency and the adsorptio...

KCoMoS2 was supported on various carbon support materials to study the effect synthesis gas conversion. Next two activated carbons with high micropore volume, a traditional alumina (?-Al2O3) and its coated form (CCA) were studied for comparison. Coating increases selectivity alcohols, but AC-supported catalysts show even higher alcohol selectivities yields, especially at temperatures where conv...
