Insects are diverse in their distribution amongst kingdom Animalia. Order Lepidotera (butterflies & moths) stands second after coloeoptera diversity. Noctuidae is one the important families of order Lepidoptera with 36 and 4200 genera it. As moths exhibit great diversity besides presence many sub-species cryptic species it has turned out to be tough conducting taxonomical studies on them. The D...

Atrazine’s adsorptive capabilities make the use of clays practical and effective. Three types organophilic modified by cationic surfactants with ability one these to adsorb atrazine in an aqueous medium are discussed this work. The modification was done cetyltrimethylammonium bromide, chloride, dodecyltrimethylammonium chloride. X-ray diffraction data indicated different lamellar expansions for...

The morphology of nano gamma alumina affects the molecule adsorption-desorption phenomena. In this case, manipulating surface area, pore volume, and size by technique preparation to control textural properties alumina. Washing synthesized boehmite gel with methanol has a significant effect. co-precipitation method was used prepare alumina, which is involved adding drop-by-drop ammonium hydroxid...
