- 中文摘要: The paper capillary permeation adsorption (PCPA) separation of 2,4-D and silvex herbicides from water by the addition of cetyltrimethylammonium bromide (CTAB) was studied. The effect of pH, CTAB concentration, and the type of PCPA treatment on separatability has been investigated. A nearly 100% separatability was obtained for each of 2,4-D and silvex at pH values larger than 7 and 5, respectively. The separatability is greater than that without an addition of CTAB. It was confirmed that 2,4-D and silvex are adsorbed as molecules on the fiber surface that contains ion pairs CTA+COO- formed by the combination of CTA+ cations with the carboxyl groups bonded in the fiber surface.
