The fate and transport of viruses in soil and aquatic environments were studied with respect to the different forces involved in the process of sorption of these viruses on soil particles. In accordance with the classical DLVO theory, we have calculated the repulsive electrostatic forces and the attractive van der Waals forces. Bacteriophages have been used as model sorbates, while different clays have been used as model sorbents. The equations used for the determination of the change in free energy for the process (deltaG) takes into consideration the roughness of the sorbent surfaces. Results indicate that attractive van der Waals forces predominate the process of sorption of the selected bacteriophages on clays.
针对病毒吸附到土壤颗粒过程中涉及的不同作用力,研究了病毒在土壤和水生环境中的归宿与迁移。根据经典的DLVO理论,我们计算了排斥性静电力和吸引性范德华力。噬菌体被用作模型吸附质,不同的黏土被用作模型吸附剂。用于确定该过程自由能变化(ΔG)的方程考虑了吸附剂表面的粗糙度。结果表明,在选定的噬菌体吸附到黏土的过程中,吸引性范德华力起主导作用。
