| 摘 要： | 目的研究硫酸铜对室内空气中低浓度甲醛的去除。方法以酚试剂分光光度法测定甲醛浓度,采用液相吸收法研究了在不同 pH 值(11.99、12.86、13.08、13.42)、硫酸铜浓度(3.0、5.0、7.0、10.0g/L)、络合剂[酒石酸钾钠与乙二胺四乙酸二钠(EDTA)]3种因素下,硫酸铜对低浓度甲醛的去除效果。结果 pH 值分别为11.99、12.86、13.08、13.42时,硫酸铜对10.0 mg/L 甲醛的去除率分别为43.82%,62.75%,69.21%,73.40%;当 pH=13.42、硫酸铜的浓度分别为3.0、5.0、7.0、10.0g/L时,对10.0mg/L 甲醛的去除率分别为51.43%,73.40%,66.36%,62.18%。当 pH=13.42、硫酸铜的浓度为5.0g/L 时,在以酒石酸钾钠与 EDTA 为络合剂的条件下,对2.0mg/L 甲醛的去除率分别为77.21%,62.51%;对10.0mg/L甲醛的去除率分别为86.54%,73.40%;对100.0mg/L 甲醛的去除率分别为96.71%,91.32%。结论 pH=13.42、络合剂为酒石酸钾钠时,5.0g/L 的硫酸...
