摘　　要：探讨了Fe3+、Cu2+、Ca2+3种金属离子对常用的15支弱酸性染料色光的影响,结果表明:Fe3+和Cu2+对弱酸性染料影响较大,Fe3+使酸性5R深蓝、酸性M-R藏青和酸性R大红色光明显变浅,使酸性N-R蓝和酸性BRL蓝色光明显偏黄;Cu2+使酸性N-R红色光偏绿偏黄,使酸性FRL红色光偏绿偏蓝,色深度下降。Ca2+对酸性染料色光影响相对较小,主要起聚集作用,染色色深度上升。Influence of Fe^3 ＋,Cu^2 ＋,Ca^2 ＋on 15 weak acid dyes were discussed,the results showed that： Fe3 ＋and Cu^2 ＋had great effect on weak acid dyes,such as the color shade of acid 5R dark blue,M-R navy blue and acid R bright red became lighter in the present of Fe^3 ＋,and the color shade of acid N-R blue and BRL blue also became more yellow. Cu^2 ＋had great influence on acid N-R red and FRL red,acid N-R red＇s color shade became more yellow,more green and FRL red＇s color shade became more blue,more green,and both of their color depth drop. Ca^2 ＋had a little effect on weak acid dyes relatively,mainly from condensation,and color depth increased.
