A new chelating resin was synthesized by immobilizing 1-(2-thiazolylazo)-2-naphthol through the -N=N- group on Amberlite XAD-1180. The resin was used for the preconcentration of Cd(II), Co(II), Cu(II), Mn(II), Ni(II), and Pb(II) ions and their determination by flame atomic absorption spectrometry (FAAS). The influences of some analytical parameters, such as the pH, volume of the sample, flow ra...

The amino acid and lipide composition of a highly active toxohormone preparation (TH2) from human malignant tissues was investigated. Approximately 80 per cent of the TH: could be accounted for as polypeptide, with leucine, alanine, glutamic, and aspartic acid being present in the highest concentrations. The remaining ~0 per cent consisted largely of phospholipides. The TH~ fraction was divided...

In this study, we compare the data of advanced geostationary radiation imager (AGRI) on board FY-4B and meteorological (AMI) GK-2A, in terms overall data, different reflectivity/brightness temperature intervals, regions, underlying surfaces. The results show that AGRI AMI are generally consistent; mean biases for reflectivity channels a range 0.50% to 1.69%, with channel VIR004 being exceptiona...

The ion exchange resin Amberlite 958 was used to investigate its behaviour on the removal of hazardous vanadium(V) from aqueous media. This investigation carried out under various hydrodynamic conditions and chemical conditions, such as variation stirring speed, pH solution, dosage, initial in temperature. Vanadium(V) uptake onto highly dependent thus, speciation this phase; process had an endo...

Abstract A solid waste sample from acidic leaching of Alluoga sedimentary rocks, SW Sinai, Egypt, was processed for and extraction U Cu respectively. This assayed 200 mg/kg 5 g/kg Cu. The present work aims to obtain free through selective alkaline uranium followed by environmentally safe glycine solution copper the resulted waste. Under studied optimum conditions efficiency attained 93% 96% Ura...

Abstract In this paper, leaching characteristics are presented, and a cost-effective process for extracting uranium, copper, cadmium from Talet Seleim’s Gibbsite is developed. H 2 SO 4 was chosen as the preferable agent based on agitation experiment’s findings. The efficiencies of U, Cu, Cd attained 95%, 90%, 89%, respectively, under investigated ideal circumstances. Kinetic study proved diffus...
