摘　　要：采用XDA-1树脂吸附固定床工艺，对CS2饱和水溶液和含CS2的空气分别进行了动态吸附性能和影响因素的研究。在室温、CS2饱和水溶液流速为40BV／h（BV为树脂床体积）、中性或弱酸性的条件下，XDA—1树脂对水中饱和CS2的吸附效率达98．1％，对CS2的吸附量可达54．0g／L。在室温和气体流速为600BV／h的条件下，XDA-1树脂对空气中CS2的吸附效率为63．9％-90．0％，对CS2的吸附量可达28．0～36．8g／L。采用水蒸气解吸和冰水冷凝可以回收84．9％-90．0％的CS2。The dynamic adsorption performances of XDA-1 adsorption resin and the affecting factors were studied in the tests of treating CS2 saturated aqueous solution and air containing CS2 in a fixed bed. Under the conditions of room temperature, solution flow rate 40 BV （ bed volume）/h, neutral or faintly acid aqueous solution, its adsorption efficiency to CS2 saturated in water is 98.1% and its adsorption capacity to CS2 is 54.0 g/L. When the experimental conditions are room temperature and air-flow rate 600 BV/h, its adsorption efficiency to CS2 in air is 63.9%- 90.0%, its adsorption capacity to CS2 is 28.0-36.8 g/L. The recovery of CS2 can be 84.9%-90.0% by steam desorption and ice water condensation.
