Description:

The influence of SAS of different chemical nature on aggregate stability and bactericidal action of nano silver colloidal solutions is investigated. Colloidal solutions of silver were obtained by restoring the argentum nitrate agent in a neutral medium. With the help of spectrophotometric method, it has been proved that such solutions are characterized by high aggregate stability compared with the use of other traditional reducing agents. Anionic SAS (sodium dodecylsulfate and sulfanol) and nonionic SAS (OS-20) increase aggregate stability of nano silver solutions, while cationogenic SAS − alcamone promotes rapid coagulation and aggregation of nano silver particles. The study of bactericidal action of the solutions to the E.coli are showed that the nano silve colloidal solution with or without presence of OS-20 and alcamone completely inhibit the growth of colonies of E.coli, that is, it’s have high bactericidal properties.
