PAC in aluminum oxide content, and how to detect it? Detection polyaluminum chloride aluminum oxide content of the method are as follows: 1, the slag weighed, pulverized, by adding hydrochloric acid solution (of known concentration) was stirred, filtered and weighing the content was calculated. 2, weighing: go to a certain amount of the slag crushed, weighed m1 grams, the sample was treated with sufficient amount 0.1molNaOH solution, filtered, washed residue, container three times, and the washings were also poured into the filtrate. Add a large amounts of hydrochloric acid solution until the precipitate is completely dissolved. Dropping ammonia to the filtrate until no more precipitate formation. The precipitate filtered off and rinsed with deionized water three times, and sufficiently dried, weighed after the weight m2 obtained dry 3,2 Al (OH), Al (OH) 3 - Al2O3, 78 × 2 102 3, Al2O3 polymerization Chloride aluminum content: (m2 × 102/156) / m1 × 100% = Al2O3 percentage content.
