Abstract
A new, simple, rapid, sensitive and selective spectrophotometric kinetic
method for Ag(I) traces determination at room temperature was elaborated in
this paper. It is based on catalytic effect of silver ions upon the oxidation
of methylene blue B (MBB) by K2S2O8 (PPS) in citric buffer (BUF) solution.
The method was confirmed by determination of Ag(I) in PbO. The obtained
results were compared to those obtained by ICP-OES method and good agreement
of results was found.
