In this work, adsorption kinetics were investigated in order to remove the acid blue 62 off the aqueous solutions using mesoporous silicate SBA-15 loaded with tannic acid (tannin-SBA-15). Nitrogen adsorption and desorption test (BET), X-ray diffraction (XRD) and Fourier transform infra-red spectroscopy (FT-IR) analysis characterize synthesized composite. The impacts of some parameters such as P...

abstractbackground and objectives:the phosphorus is second limiting nutrient in soil for crop production after nitrogen. mobility and availability of phosphorus (p) in soils is affected by phosphorus desorption characteristics. information about the effect of organic matter on kinetics and thermodynamics of p desorption in calcareous soils of east azerbaijan province is limited. the objective o...

The present study was conducted to know the prevalence of Salmonella and E.coli serovars in pigs at different localities of Andhra Pradesh as non typhoidal Salmonella strains and E.coli are important causes of reportable food borne infection. Among 101 faecal samples screened six isolates of Salmonella ie. S. derby (3) , S.typhimurium (2) and S.typhisuis (1) and twenty isolates of E.coli viz. 0...
