AVALIAÇÃO ESPECTROFOTOMÉTRICA DAS FORMAS CR+3, CRO4 -2 E CR2O7 -2
A spectrophometric study of the speciation of the chemical forms Cr+3, CrO4-2 and Cr2O7-2 was carried out on a wide interval of pH (from 2,0 to 12,0) in a Britton-Robinson buffer solution. The absorption spectra of the ultraviolet and visible regions are well defined and show bands in the two spectr...
