Deoiled mustard obtained from local oil mills has been used as an inexpensive and effective adsorbent for the removal of indigocarmine dye from industrial effluents. The influence of various factors on the adsorption capacity has been studied by batch experiments. The adsorption studies validate both Langmuir and Freundlich adsorption isotherms. Thermodynamic parameters such as DeltaG degrees, DeltaH degrees, and DeltaS degrees for the adsorption process were calculated, which indicated the feasibility of the adsorption process. Desorption profiles revealed that a significant portion (85%) could be desorbed from deoiled mustard by using 30% glycerol as eluting agent.
从当地油厂获得的脱油芥菜已被用作一种廉价且有效的吸附剂，用于从工业废水中去除靛卡红染料。通过批量实验研究了各种因素对吸附能力的影响。吸附研究验证了朗缪尔和弗伦德利希吸附等温线。计算了吸附过程的热力学参数，如ΔG 度、ΔH 度和ΔS 度，表明吸附过程是可行的。解吸曲线表明，使用 30%的甘油作为洗脱剂可以从脱油芥菜中解吸 85%的染料。
