用动态法在不同的 p H值与环境条件下 ,测定了页岩粉末对杀虫双的吸附量。在 p H为 5 .0 0～ 8.5 0 ,温度在 2 6～ 90℃时 ,60～ 80目的页岩粉末的弱吸附为 1.15～ 1.86mg/g干样 ,可逆吸附为 0 .99～ 5 .3 1mg/g干样 ,不可逆吸附为 0 .69～ 4.90 mg/g干样。
Dynamic method was used to determine the adsorption capacity of shale powder to insecticidal double under different p H values and environmental conditions. The weak adsorption of shale powder of 60 ~ 80 mesh was 1.15 ~ 1.86 mg / g dry sample with reversal adsorption of 0.99 ~ 5 at p H of 5.0 ~ 8.5 0 and temperature of 26 ~ 90 ℃. 3 1mg / g dry sample, irreversible adsorption of 0.69 ~ 4.90 mg / g dry sample.
