(a) This method covers the colorimetric determination of zinc in industrial water and industrial waste water. Interferences from many metals are eliminated or minimized in this method. (b) A large portion of precipitated or suspended zinc is dissolved and measured in the test when a shaken sample is analyzed. Total zinc will be determined if insoluble zinc compounds are solubilized by acid treatment as given in Note 2. Dissolved zinc is determined on a filtered sample.
