Naturally occurring colloids such as humid acids represent types of polyelectrolytes which affect the environmental quality of water. Artificial polyelectrolytes are often used as flocculants for treatment of colloidal water as well as water which contains suspended materials. Anionic polyelectrolytes, such as potassium poly (vinyl sulfate) and polystyrenesulfonate are, respectively, used as dispersants for concentrated ceramic slurries and that for coal water mixtures-the latter of which represents a promising alternative fuels. As a result, urgent needs have developed for rapid and sensitive analytical methods for the detection and measurement of polyelectrolytes in environmental water and for the process control of dispersants in concentrated ceramic slurries and coal water mixtures. In this paper, we will describe polyelectrolyte- and surfactant-sensitive sensor based on quartz crystal microbalance (QCM) method for the determination of polyelectrolytes and surfactants. The response of QCM sensor based on the Au film immobilized with a SH(CHィイD22ィエD2)ィイD210ィエD2COOH to a cationic polyelectrolyte was examined. The sensor did not respond to cationic polyelectrolytes in the concentration range from 10ィイD1-5ィエD1 to 10ィイD1-2ィエD1 M. Furthermore, QCM sensor based on the Au film immobilized with SH(CHィイD22ィエD2)ィイD23ィエD2NHィイD22ィエD2 HCl did not respond to anionic polyelectrolytes in the concentration range form 10ィイD1-5ィエD1 to 10ィイD1-2ィエD1 M.

天然存在的胶体，如湿润酸，代表影响水的环境质量的聚电解质类型。人工聚电解质常用作处理胶体水以及含有悬浮物的水的絮凝剂。阴离子聚电解质，如聚（乙烯基硫酸）钾和聚苯乙烯磺酸盐，分别用作分散剂的浓缩陶瓷浆料和煤水混合物，其中后者代表了一个有前途的替代燃料。因此，迫切需要开发快速和灵敏的分析方法，用于检测和测量环境水中的聚电解质，以及用于浓缩陶瓷浆料和水煤浆混合物中分散剂的过程控制。本文介绍了一种基于石英晶体微天平（QCM）法的表面活性剂和聚电解质的双灵敏传感器。考察了以SH（CH_（2-））D_2 2-D_2-COOH为固定剂的Au膜为基的QCM传感器对阳离子染料的响应。传感器对浓度范围为10 μ g/L D1-5 μ g/L D1至10 μ g/L D1-2 μ g/L D1 M的阳离子聚电解质无响应。此外，基于固定有SH（CH_（22）CN_（22）D_2）CN_（23）D_2 NH_（22）CN_（22）D_2 HCl的Au膜的QCM传感器在10 μ mol/L D_1 -5 μ mol/L D_1至10 μ mol/L D_1 -2 μ mol/L D_1 M的浓度范围内对阴离子聚电解质没有响应。
