摘　　要：用静态吸附法考察粉末活性炭对水中三烯丙基异氰脲酸酯(CAIC)的吸附行为,采用单因素分析法对活性炭吸附化工废水中TAIC的工艺条件进行研究。实验结果表明,在TAIC模拟废水中,其TAIC初始浓度为800 mg/L,pH为7,在温度为298 K、转速为150 r/min的条件下,当活性炭的投加量达到4.4 g/L,吸附反应时间为50 min时,TAIC的去除效率最高为96.17%;对于实际废水,其TAIC初始浓度为1 500 mg/L,溶液pH为3,在温度为298 K、转速为150 r/min的条件下,当活性炭投加量达到10 g/L,吸附反应时间为2 h时,TAIC的去除效率最高为46.8%。这也是由于实际废水组分复杂,其他有机物存在一定的吸附竞争机制。Under the liquid conditions, the adsorption of triallyl isocyanurate（TAIC） on the powdered acti- vated carbon was examined by the static adsorption method. Moreover, the process conditions of TAIC adsorption on the powdered activated carbon in chemical wastewater was studied by the univariate analysis method. The re- suits showed that the removal efficiency of TAIC in simulated wastewater with initial concentration of 800 mg/L and pH of 7 was up to 96. 17% when the temperature, rotational speed, dosage of the activated carbon and ad- sorption reaction time were 298 K,150 r/min,4.4 g/L and 50 min, respectively. While in practical wastewater with initial concentration of 1 500 mg/L and pH of 3, the TAIC removal efficiency was up to 46.8% when the temperature, rotational speed, dosage of the activated carbon and adsorption reaction time were 298 K, 150 r/rain, l0 g/L and 2 h, respectively. This was due to the complicated components and competitive adsorption mecha- nism of other organics, i
