Abstract: The oscillatary behavior of diacetone alcohol(DA)-KIO_3-H_2O_2-H_2SO_4-Ce~(3+) system has been studied.The system may oscillate in the concentration ranges of H_2SO_4 0.11—0.24, KIO_3 0.019—0.048; Ce~(3+) 5.95×10~(-4)—3.57×10~(-3), DA 0.4—3.22 and H_2O_2 0.40—1.99 mol·dm~(-3) respectively.
Using Hg_2SO_4 electrode as the reference electrode, the potential of I~- and the redox potential show oscillatary wave behavior in XWT balance recorder.
According to our expreimental results, We may said seen that ...
