1.用测量微分电容的方法测量各种典型有机表面活性剂在中性及碱性溶液中的吸附特性,井找出当溶液碱化时表面活性剂吸附特性的变化可用活性粒子的存在形式及双电层结构的基本理论加以解释。 2.在所测各种化合物中,佩列加(聚环氧乙烷型表面活性剂)及四丁基铵盐在碱性溶液中能在很宽的电势范围内在电极上吸附,尤其是前者的脱附电势高达—1.8伏特以上,在浓碱中的溶解度也较大,应是较有希望的添加剂。
1. Measuring the differential capacitance method to measure the adsorption properties of various typical organic surfactants in neutral and alkaline solutions and to find out when the solution is alkalized, the change of the adsorption properties of the surfactants can be found in the form of active particles and The basic theory of electric double layer structure is explained. 2. Among the compounds tested, pergalline (polyethylene oxide type surfactant) and tetrabutylammonium salt can be adsorbed on the electrode in alkaline solution in a wide range of potentials, especially the former Desorption potential of up to -1.8 volts or more, the solubility in concentrated alkali is also larger, should be a more promising additive.
