method for the continuous measurement of cyanide in the waste water of iron and steel industry and apparatus therefor.

摘要

in order to eliminate the concentration of free cyanide in the presence of thiosulfate thiosulphate by eliminating interference due to two successive steps, it is.namely, as the sum of currents due to cn and s2o3 -- the potential corresponding to the maximum value of the peak position of cn - ion peak due to the single s2o3 -- at the same potential.after removal of cyanides by the action of formaldehyde cyanohydrin forming a signal which is not technique.application to the continuous measurements of cyanide in the waste water of the iron and steel industry.
