Synthesis of 2-pyridinecarboxylic acid by oxidation of potassium dichromate;

Determination of purity of potassium dichromate by Coulometric Titrimetry;

Study of DNA damage induced by potassium dichromate and glutathione with atomic force microscope;

Study on the Opening and Surface Treatment of CNTs with K_2Cr_2O_7;

TOSICITY OF K_2Cr_2O_7 TO GERIODAPHNIA QUADRANGULA(O.F.MULLER);

Objective To observe the germicidal efficacy of compound potassium bichromate acid solution and its influencing factors.

In terms of the reductibility of phosphorous acid,the phosphorous acid was oxidized with potassium bichromate in sulfuric acid.

The comparison of monitoring COD in water with rapid monitoring method and potassium dichromate method is finished.

Based on the operation and management experience of on-line COD_(Cr) analyzer,several suggestions are put forward,including replacing ferrous ammonium sulfate by potassium hydrogen phthalate as range-measured solution,replacing zero offset by beginning offset,and inspecting the compatibility of analyzer to water quality when the potassium dichromate method is not used.

the improved method had advantages of fewer quantity of acid,less heating time and low cost over the potassium dichromate method of national standard.
