It has been found that the real value of decolorizing power of active carbon can be determined by the TES 1012 procedure very simply and exactly, when it is carried out under the following experimental conditions.(1) Distilled water : In strict sense.(2) Glass flask and implements : After washing with H_2SO_4-K_2Cr_2O_7 solution, must-be thoroughly washed with steam.(3) Test active carbon : Must be neutralized by boiling and washing with distilled water.(4) Drying : Neutral test active carbon must be dried to a constant weight.(5) Temperature of measuring : Constant; but if not, it is to be noted.(6) Peeparation of test solution : Test solution must be prepared immediately before each test and in the same color as the standard.(7) Test solution : Test solution must contain the buffer solution (pH 6.8) and original test solution, and must be meutralized as enough as possible.(8) pH of original active carbon : Must be measured and noted.
