本文件规定了各种类型水中总氰化物测定的操作定义方法，如饮用水、地下水、地表水、废水、冶金加工尾矿回收溶液、堆浸贫溶液、矿浆尾矿滤液和浸出溶液，氰化物浓度为5？g/l至2000 mg/l，以未稀释样品中的氰化物离子表示。可通过降低灵敏度来扩展应用范围（图A.1.）。购买本文件时可获得的所有当前修订均包含在购买本文件中。

This document specifies operationally defined methods for the determination of total cyanide in various types of water such as drinking water, ground water, surface water, wastewaters, metallurgical processing tailings reclaim solution, heap leach barren solution, mill slurry tailings filtrate and leaching solutions, with cyanide concentrations from 5?g/l to 2 000 mg/l expressed as cyanide ions in the undiluted sample. The range of application can be extended by reducing the sensitivity (Figure A.1.).All current amendments available at time of purchase are included with the purchase of this document.
