摘要
PROBLEM TO BE SOLVED: To provide a method for fully separating total cyanogen in an aqueous solution containing a heavy-metal cyano-complex through distillation and simply and accurately determining it. ;SOLUTION: The quantifying method is comprised of a process to distill an aqueous solution, containing a heavy-metal cyano-complex in the presence of a reducing agent to generate hydrogen cyanide, a process for making an alkali absorbent absorb the generated hydrogen cyanide, and a process for measuring the amount of cyanogen in the absorbent which has absorbed the hydrogen cyanide.;COPYRIGHT: (C)2001,JPO
