New Method for Removal of Microorganisms from Water Based on Pyridinium-Type Resin

水消毒在保护公众健康方面是重要的。最流行的方法是用氯和其他相关化学品处理，但三卤甲烷和其他致癌物质的形成是该过程的严重缺陷。据报道，这些有机卤素化合物发生生物缩合，这导致严重的环境污染。该实验室最近的一份报告表明，不溶性吡啶鎓型树脂通过与表面上的许多细菌细胞接触而强烈捕获它们。本研究项目的目的是开发一种新的、可靠的、有效的基于不溶性吡啶型树脂的从水中去除微生物的方法，该方法不产生任何有毒化学物质，对环境不造成污染。随着树脂中吡啶基团含量的增加，树脂的亲水性和吸水膨胀度的增加，树脂的捕集能力增强 ...更多信息 在矩阵中。疏水性细菌和亲水性细菌在树脂与细菌细胞的捕获作用上表现出明显的差异。对于疏水性细菌，树脂与细胞之间的静电相互作用和疏水相互作用显得很重要。对于亲水性细菌，提出了其他因素，例如溶剂（水）介导的力和流体动力。另一方面，相应的线性聚合物，即，发现可溶性吡啶鎓型聚合物表现出抗菌活性。此外，可溶性吡啶鎓型聚合物。发现其是用于微生物细胞悬浮液的优良聚合物凝结剂。这些现象似乎与吡啶型树脂捕获微生物细胞的强能力有关。基于这些实验观察，不溶性吡啶型树脂被证明是一种优良的材料，用于去除废水中的微生物，而不产生有毒化学物质如三卤甲烷，并且对环境没有污染。少

Water disinfection is important in the protcetion of public health. The most popular process is the treatment with chlorine and other related chemicals, but the formation of trihalomethanes and other carcinogens is a serious defect in this procedure. These organohalogen compounds are reported to undergo biocondensation, which results in a serious pollution of the environment. A recent report from this labolatory has demonstrated that insoluble pyridinium-type resin strongly captures many bacterial cells on the surface by contact with them. The purpose of this research project is to develop a new, reliable, and effective process for termoval of microorganisms from water based on the insoluble pyridinium-type resin, which does not produce any toxic chemical substances and does not exert pollution upon the environment. The capturing ability of the resin increased with the content of the pyridinium group in the resin, as well as hydrophilicity and high degree of swellin in water of the res … More in matrix. Hydrophobic bacteria and hydrophilic bacteria showed distinct difference in the capturing interaction between the resin and bacterial cells. With hydrophobic bacteria, electrostatic interaction and hydrophobic interaction between the resin and cells appeared to be important. with Hydrophilic bacteria, other factors such as solvent (water) mediated forces and hydrodynamic forces were suggested. On the other hand, the corresponding linear polymer, i.e., soluble pyridinium-type polymer was found exhibit antibacterial activity. In addition, the soluble pyridinium-type polymer was. found to be an excellent polymeric coagulant for the suspension of microbial cells. These phenomena appeared to be related with the strong ability of the pyridinium-type resin to capture microbial cells. Based on these experimental observations, the insoluble pyridinium-type resin was demonstrated to be an excellent material for removal of microorganisms from waster without production of toxic chemicals such as trihalomethanes, and with31t environmental pollution.
