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

水消毒在保护公共卫生方面起着重要作用。最流行的工艺是用氯和其他相关化学品处理，但三卤代甲烷和其他致癌物的形成是这一过程的一个严重缺陷。据报道，这些有机卤素化合物会发生生物缩合，造成严重的环境污染。该实验室最近的一份报告显示，不溶的吡啶型树脂通过与细菌接触，强烈地捕获了表面的许多细菌细胞。本研究项目的目的是开发一种新的、可靠的、有效的从水中杀灭微生物的工艺，该工艺以不溶于水的吡啶型树脂为基础，不产生任何有毒化学物质，对环境不造成污染。树脂的捕集能力随树脂中吡啶基含量的增加而增加，随RES…的亲水性和水中溶胀度的增加而增加更多的是矩阵。疏水性细菌和亲水性细菌在捕获树脂与细菌细胞之间的相互作用方面表现出明显的差异。对于疏水性细菌，树脂和细胞之间的静电相互作用和疏水相互作用似乎是重要的。对于亲水性细菌，还提出了其他因素，如溶剂(水)介导力和流体动力力。另一方面，发现相应的线型聚合物，即可溶性吡啶型聚合物具有抗菌活性。此外，还合成了可溶性的吡啶型聚合物。被发现是微生物细胞悬浮液的极好的聚合凝聚剂。这些现象似乎与吡啶型树脂捕获微生物细胞的能力很强有关。根据这些实验观察，不溶性吡啶型树脂被证明是一种去除废水中微生物的优良材料，不产生三卤代甲烷等有毒化学品，对环境造成31t的污染。较少

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.
