Influence of structure of functional groups in direct dye molecules on the process of interaction with ions and nanosized silver particles

The results of a study by spectrophotometric titration of the interaction of ions and nanosized particles of silver with a number of direct dyes containing groups with different electronic and steric effects in the molecules are presented. The patterns of interaction due to the influence of the structure offunctional groups are found. The conclusions made are confirmed by quantum chemical calculations. © 2019 Ivanovo State Polytechnic University. All rights reserved.
