摘要：
Suitable colour reactions can be used to determine the type of additive used in gypsum binders which have been modified with polysaccharides. Quantitative determination of the polysaccharides added can be carried out photometrically after conversion with suitable reagents. The blue colour of the starch-iodine complex is utilized for photometric determination of etherified starches in gypsum binders. Methylcelluloses can be converted with diphenylamine at 108-degrees-C to give a blue colour-complex. Carboxymethylcellulose can be determined quantitatively with 5% phenol solution after hydrolysis with sulphuric acid.
