Abstract

Many industrial and chemical dyes are used in many industrial processes, a variety of different uses. Among the most important of these industries, fabric dyeing, many textiles, papermaking, printing and leather processing, and most food products, and other industries, use industrial dyes, and the waste emitted from these dyes in most industries in which most of the polluted waste resulting from these remnants is produced factories. Therefore, the best methods were adopted to treat and dispose of these dyes in order to preserve the aquatic environment .In the current study, the adsorption characteristics of two dyes, Maxillon blue (GRL) and Direct yellow (DY12), from an aqueous solution were evaluated. The effect of several factors, for example, initial concentration, pH solution, temperature, adsorbent mass, and equilibrium time, have been study. The adsorption capacity and percentage of color removed upraised by elevating contact time and surface area, also elevated by the upraised temperature solution for GRL and DY12, and also the adsorption efficiency decreased by the raised adsorbent dosage. The optimum equilibrium for contact time to be completed is found to be (60 min) 1 hour. It is essentially due to the saturation of the active site that does not let further adsorption to take place. The adsorption was proved through utilizing (FT-IR) and (F.E-SEM) analysis. In addition, TGA appears that the NTADCIP/P (AA-co-AM) composite is stable in high temperatures. GRL adsorbent surfaces best adsorption found to be at pH = 10. In fact, adsorption was found to increase through the rise in solution pH.  However DY12 maximum dye adsorption was found to be at pH = 3.  The applicability of isotherms adsorption to study the adsorption behavior has to been analyzed via isotherm models Freundlech and Langmuir were utilized to illustrate the experimental model and isotherm's constants. It was found the Freundlech model gives the best fits when compare with Langmuer isotherm for two dyes.

介绍一种新的化学除染料方法:从水溶液中去除Maxillon Blue和Direct Yellow
许多工业和化学染料被用于许多工业过程中,有各种不同的用途。在这些行业中最重要的行业中,织物染色、许多纺织、造纸、印刷和皮革加工、大多数食品和其他行业都使用工业染料,而在大多数行业中,这些染料排放的废物大部分由这些残留物产生的污染废物都是工厂生产的。因此,为了保护水生环境,我们选择了最佳的方法来处理和处理这些染料。本研究评估了两种染料Maxillon blue(GRL)和Direct yellow(DY12)在水溶液中的吸附特性。研究了初始浓度、pH溶液、温度、吸附剂质量和平衡时间等因素的影响。GRL和DY12的吸附容量和脱色率随着接触时间和表面积的增加而增加,温度溶液的升高也会增加,吸附剂用量的增加也会降低吸附效率。发现待完成的接触时间的最佳平衡为(60分钟)1小时。这主要是由于活性位点的饱和,不允许发生进一步的吸附。利用(FT-IR)和(F.E-SEM)分析证实了吸附作用。此外,TGA显示NTADCIP/P(AA-co-AM)复合材料在高温下是稳定的。发现GRL吸附剂表面的最佳吸附是在pH=10时。事实上,发现吸附量随着溶液pH的升高而增加。然而,DY12对染料的最大吸附量在pH=3时。必须通过等温线模型分析等温线吸附对研究吸附行为的适用性。Freundlech和Langmuir用于说明实验模型和等温线常数。发现Freundlech模型与Langmuer等温线对两种染料的拟合最好。
