摘要
测定了国产高分子小球GDX-102对水中微量有机氯农药(β-666、p,p’-DDE和p,p’-DDT)的吸附容量和富集效率,选取了动态富集最佳水样流速.结果表明,GDX-102对上述三种有机氯农药均有较大的吸附容量,其数值分别为14.2mg/g(β-666)、22.3mg/g(p,p’-DDE)和31.4mg/g(p,p’-DDT).在实验条件下,水样流速在0—60ml/min范围内变化时,对GDX-102的富集效率影响甚小,富集效率接近100％,因此,GDX-102可应用于环境水样中微量有机氯农药的现场采样富集.
The capacities and efficiencies of the adsorption of organochlorine pesticides in aqueous solutions by macro-molecular porous resin GDX-102 were measured. The optimum dynamic rates of water samples were determined. The experimental results show that GDX-102 is possessed of great adsorption capacities and high adsorption efficiencies, which is slightly influenced by flow rate of water sample and therefore it is useful for field sampling of environmental water.
