In this paper, a new method for the determination of cysteine by potassium dichromate spectrophotometry is established. H 2 SO 4 medium, has strong oxidation. Potassium can react with hydrosulfuryl(-SH) in cysteine, which makes fade, and fading degree proportional to amount added. Therefore, content be quantitatively determined determinating decrease value absorbance. The various influencing fa...

. The absorbances of five concentrations of potassium dichromate in 0.001 ]l.f perchloric aCid have been determined at eight wavelengths in the ultraviolet on the National Bureau of Standards Institute for Materials Research high-accuracy spectrophotometer. Four of the wavelengths-235, 257, 313, and 3.50 nm-correspond to absorbance maxima or minima in the HCrO,spectrum and are useful wavelength...

Introduction: Severe industrial diseases result from the hepatic accumulation of mercury, cadmium or chromium in humans and on the other hand cadmium and dichromate and mercuric salts may induce lung or kidney cancer. Acute or chronic CdCl2, HgCl2 or dichromate administration induces hepatic and nephrotoxicity in rodents. Oxidative stress is often cited as a possible cause of metal induced cell...

Element recovery from the Martian regolith using ionic liquids (ILs) is an active area of research within field in-situ resource utilization. In this work, we performed a classical molecular dynamics (MD) simulation study to better understand solvation thermodynamics and structures potential cationic anionic species originating in two select ILs, i.e., 1-ethyl-3-methylimidazolium acetate ([emim...
