The effectiveness of acid activated sawdust in absorbing D-Brown EGP and Lurazol Brown PM dyes from aqueous solutions was studied as a function of agitation time and initial dye concentration. The experimental data were fitted to Langmuir and Freundlich isotherm and found that adsorption process follows both the isotherms. The values of Langmuir and Freundlich constants indicate favorable and beneficial adsorption. Saw dust is an excellent low cost adsorbent of colored organic anions and may have significant potential as a color removal from tannery wastewater.
研究了酸活化锯末从水溶液中吸附D-布朗EGP和鲁拉唑尔棕PM染料的效果与搅拌时间和初始染料浓度的关系。将实验数据拟合到朗缪尔等温线和弗伦德里希等温线，发现吸附过程符合这两种等温线。朗缪尔常数和弗伦德里希常数的值表明吸附是有利的。锯末是一种优良的低成本有色有机阴离子吸附剂，在制革废水脱色方面可能具有巨大潜力。
