活性红195在中性电解质溶液中的聚集行为
|
摘要
为研究染料聚集行为及其对染色上染率的影响,将不同质量浓度的6种中性电解质加入到活性红195染料溶液中,借助紫外-可见分光光度计和激光粒度仪等研究了活性红195染料在不同电解质溶液中的聚集行为,并探讨了电解质对染色上染率的影响。结果表明:随着电解质质量浓度的增大,染料聚集程度增大;常温下,6种金属离子对染料聚集的影响程度依次为Al~(3+)> Ca~(2+)> Mg~(2+)> K~+> Na~+> Li~+;电解质中所含金属离子的离子半径越大、化合价越高,越易引发染料聚集,其中金属离子的化合价是影响染料聚集的主要因素;染色时染料聚集程度越大,上染率越高。
In order to study the aggregation behavior of Reactive Red 195 and its effect on dye uptake,six neutral electrolytes with different concentrations were added into the Reactive Red 195 dye solution.The aggregation behaviors of Reactive Red 195 in different electrolyte solutions were studied by means of UV-Vis spectrophotometer and laser particle size analyzer,and the influence of different electrolytes on the dye uptake of Reactive Red 195 was investigated. The results show that with the increase of the electrolyte concentration,the degree of dye aggregation increases. At room temperature,the degree of influence of the six metal ions on dye aggregation is Al~(3+)> Ca~(2+)> Mg~(2+)> K~+> Na~+> Li~+. The degree of dye aggregation is enhanced with the increase in ionic radius and valence of metal ions. Among them,the valence of metal ions is the main factor influencing dye aggregation. During dyeing process,the dye uptake is enhanced with the increase of dye aggregation.
