| dc.description.abstract | Methods for trace analysis of chromium as Cr3+ were investigated, using differential pulse polarography in various media. Determination at the ng/ml-μg/ml range can be carried out in KCl/HCl, KCNS/HOAc, and other media. Total concentration of chromium in a solution containing Cr3+ and HCrO4 - can be determined in KCNS/HOAc, and it is found that HCrO4 - can be converted quantitatively to Cr3+. The relative quantity of HCrO4 - and Cr3+ can be determined by the difference between the total chromium concentration and the concentration of HCrO4 -. The sensitivity (12.5 ng/ml) and accuracy of this method is better than the method that determines total chromium as HCrO4 -. © 1988 Springer-Verlag. | |
