The invention belongs to the field of detection and particularly relates to a method of detecting trichloromethane and carbon tetrachloride in chlorinated polypropylene and a method for measuring the contents of the trichloromethane and the carbon tetrachloride in the chlorinated polypropylene. The invention aims at providing the method of detecting the trichloromethane and the carbon tetrachloride in the chlorinated polypropylene and the method for measuring the contents of the trichloromethane and the carbon tetrachloride in the chlorinated polypropylene. The methods have the advantages that a detection result is accurate, and accurate data can be provided for adjusting the production process and monitoring the quality of a product. In the method, a gas chromatograph is used for detection, and the method comprises the following steps: (a) preparing a standard solution; (b) preparing a sample solution; (c) adjusting the chromatographic condition and injecting the standard solution and the sample solution according to a conventional method; and (d) determining.
Description
technical field [0001] The invention belongs to the detection field, and in particular relates to a detection method and a content determination method suitable for chloroform and carbon tetrachloride in chlorinated polypropylene. Background technique [0002] Chlorinated polypropylene (CPP for short) is a chemically modified product of polypropylene (PP) containing CL groups in its structure. It has good wear resistance, aging resistance and acid resistance. It has become a chlorinated polypropylene One of the important products of modification, it is mainly used in the fields of coatings, adhesives for polypropylene films, adhesives for paints for polypropylene products, and vehicle for inks, and has shown good application prospects. [0003] The existing CPP production method mainly uses the solution chlorination method. In the past, carbon tetrachloride was used as a solvent. Later, in order to meet the requirements of the "Montreal Protocol on Substances that Deplete th...
