A field oriented and economical method of coprecipitation of trace elements like Al, Au, Bi, Cd, Co, Cu, Fe, Mo, Ni, Pb, Pd, Ti, V, W, Zn and REE has been developed. A novel reductant D-glucose, reduces KMnO(4) in solution to form a precipitate of MnO(2.) Two liters of clear natural water sample is adjusted to pH 3.5-4.0, and is treated with 10 ml of 1%(More)
The literature review on agriculture-child nutrition linkage indicates that the evidence base is weak and inconclusive (Kadiyala et al., 2013). This paper explores the possible linkages between agricultural prosperity with rural child nutrition at the macro level, controlling for sanitation and safe drinking water, using panel data fixed effects and random(More)
A cold dissolution procedure for the determination of uranium in various geological materials like rocks, minerals, soils etc., has been described. Samples are allowed to react with HF and HNO(3) at room temperature overnight. Boric acid is added to complex excess fluoride ions. From the clear solution thus obtained, uranium is determined directly in laser(More)
