CHROMIUM SPECIATION IN ORGANIC FERTILIZERS BY SPECTROPHOTOMETRY
In the present study a spectrophotometric method for Cr(VI) determination in organic fertilizers, especially those from tanning industry residues, is proposed. Conditions for chromium extraction, extract clean-up and analytical characteristics of the method were established. The method is based on t...
