电解质对溶液中活性染料聚集的影响
Effects of Electrolytes on the Aggregation of Reactive Dyes in Aqueous Solution
摘要
Abstract
It's very important for developing new salt-free dyeing technology that knowing the theory of e-lectrolyte changing the distribution status of dyes and fostering the dye molecules to dye fiber in aqueous solution. The principle of electrolytes promoting the aggregation of dye molecules in aqueous solution was investigated through UV -Vis absorption spectroscopy.When the concentration of electrolytes was less than or equal to 1mol/L,the ability to promote the aggregation of dye molecules of potassium ions which could combine with eight water molecules was better than that of sodium ions and magnesium ions which could combine with six water molecules;when the concentration of electrolyte was equal to 2mol/L,the ability to promote the aggregation of dye molecules of magnesium ions which could more stably combine with water molecules was better than that of sodium ions and potassium ions,indicating that the ability to promote the aggregation of dye molecules in solution was related to the number of combined water molecules, the more number of water molecules electrolytes could combine, the stronger the ability to promote the aggregation of dye molecules.关键词
