Two simple spectrophotometric procedures for the quantitative estimation of hypochlorite in commercially available sodium hypochlorite solutions are presented. One method is based directly on the absorbance of hypochlorite in alkaline aqueous media. The other method takes advantage of the quantitati
Electronic spectral behavior of aqueous polyvinylpyrrolidone solutions have been investigated by UV-vis spectrophotometry. n r p\* electronic excitations of the polymer were observed to shift longer wavelengths with a variety of denaturing agents. The shifting effect of denaturing agents on the l ma
