Cyanide is highly toxic, industrial emissions, etc. can cause it to enter water bodies, seriously threatening ecology and human health. This standard specifies the steps from sample collection, distillation pretreatment, to the use of specific reagents to develop color and determine the total cyanide content by titration or Colorimetry.
