Analytical application of the reaction system methylene blue B-K2S2O8 for the spectrophotometric kinetic determination of silver in citric buffer media
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)...

| Summary: | 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. [Projekat Ministarstva nauke Republike Srbije, br.
