Foreword

This standard is drafted in accordance with the rules given in GB/T 1.1-2009. This standard replaces GB 14591-2006 "Water treatment agent polymerization of ferric sulfate", compared with GB 14591-2006 main technical changes as follows. --- the nature of the standard from mandatory to recommend; - the classification of products, the class I and II products were modified to first-class goods and qualified products (see 4.2,.2006 version of 4.2); --- modified the solid iron content of solid iron sulfate products from "≥ 19.0" to "≥19.5" (see 4.2,.2006 version 4.2); - modified the salt base of qualified products (see 4.2, 4.2 of.2006); - modified the pH of the product (see 4.2, 4.2 of.2006); - modified insoluble indicators (see 4.2, 4.2 of.2006); --- increase the qualified products such as arsenic, lead, cadmium, mercury, chromium and other indicators, and modified first-class arsenic, lead, cadmium, mercury, chromium and other indicators (see 4.2, 2006 version 4.2); Increased atomic fluorescence spectrometry for arsenic (see 5.8.1), deletion of arsenic spot method (see 5.7.2 of.2006); The determination of lead and cadmium content was modified by flame atomic absorption spectrometry after extraction (see 5.8, 5.9,.2006, 5.8). - increased atomic fluorescence spectrometry (see 5.10.1), the spectrophotometric method was removed (see 5.10.1,.2006); --- modified the determination of chromium (see 5.11,.2006 version 5.11); - Added atomic absorption spectrometry to measure zinc and nickel (see 5.12, 5.13).
