Abstract

The process of flocculation of a calcium-magnesium solid phase formed in an aqueous-salt solution with the introduction of calcium-containing precipitants using polyacrylamide, cationic and anionic acrylamide copolymers was studied. With the introduction of polymers, an increase in the dispersion settling rate was observed in the concentration range of 0.5–3.0 mg/g, to a greater extent for the anionic copolymer. In the presence of an amine-containing surfactant, the sedimentation rate increased with the introduction of polymers by a factor of 1.1–1.3 compared to dispersions without surfactants. Using an anionic copolymer as an example, it was shown that the adsorption of amine and the sedimentation rate of dispersion increase with the increase of the polymer molecular weight. It was found that the concentration of the anionic copolymer and the pH of the medium also influence the adsorption of amine. Based on the obtained data, an effective method of water-salt solutions purification from amine-containing surfactants and magnesium salts (purification degree 99.5–99.8 %) that can be used at mining and processing enterprises was developed.
丙烯酰胺(co)聚合物和低分子量含胺表面活性剂二元体系在盐水介质中的吸附和絮凝性能
研究了聚丙烯酰胺、阳离子丙烯酰胺共聚物和阴离子丙烯酰胺共聚物引入含钙沉淀剂对水-盐溶液中形成的钙镁固相的絮凝过程。随着聚合物的引入,在0.5 ~ 3.0 mg/g的浓度范围内,分散沉降速率增加,阴离子共聚物的增加幅度更大。在含胺表面活性剂存在的情况下,与不含表面活性剂的分散体相比,聚合物的引入使沉降速率增加了1.1-1.3倍。以阴离子共聚物为例,结果表明,随着聚合物分子量的增加,胺的吸附量和分散体的沉降速率均增加。结果表明,阴离子共聚物的浓度和介质的pH值对胺的吸附也有影响。在此基础上,提出了一种有效的从含胺表面活性剂和镁盐中提纯水盐溶液的方法(纯化度为99.5 ~ 99.8%),可用于矿山和加工企业。
