摘    要:利用Al-Ferron逐时络合比色法分析了聚合硅酸硫酸铝液体样品及其稀释后的水溶液在各种条件下的铝形态。结果表明:聚合硅酸硫酸铝液体样品中含有约占总量1/3的多羟基配合物,且受碱化度影响很小;稀释和提高pH值使聚合硅酸硫酸铝趋于聚集成更大的分子;水中杂离子则使聚合硅酸硫酸铝的结构形态随pH值的变化幅度减小,多羟基配合物组分增加。

关 键 词:聚合  硅酸  硫酸铝  Ferron逐时络合比色法  羟基  组分  碱化度  高pH值  样品  水溶液

Abstract:The aluminium species of PASS at aqueous solution were analyzed by using Al-Ferron complex timed colorimetric method The results showed that a considerable amount of Al b was found in PASS, which was hardly affected by its bacisity PASS tended to aggregate to form larger molecules either in a dilution state or by increasing pH The hetero-ions in tap water lessened the discrepancy of aluminium species in PASS aqueous solutions caused by pH, and increased the amount of Al b
Keywords:PASS  aluminium species  Al-Ferron complex timed colorimetric method
