the process of sampling of cynide

  • Sampling and Analytical Methods Cyanide

    The sample is drawn through a cassette containing a 37-mm mixed cellulose ester membrane filter ahead of a midget impinger containing 10 mL of 0.1 N NaOH. A flow rate of 1.0 L/min and a minimum sampling time of 60 minutes are recommended. the filter is used to collect particulate cyanide while the impinger collects HCN gas.
