In this research, two biocomposite materials, namely Amberlite IRA-400 Cl resin/A. campestris and Amberlite 4200 Cl resin/A. campestris, were used to perform the biosorption of Brilliant Blue G from aqueous solution. The biosorption of dye was evaluated by using a batch system. In addition, the effect of some physicochemical and kinetic parameters of the medium such as pH, temperature, contact time and initial concentration was determined. In this research, pH (3–11), adsorbent dosage (0.3 g), initial dye concentration (10–150 mg L−1), temperature (298–318 K) and contact time (10–95 min) were investigated. In the 95th minute, biosorption reaches a maximum of 137.18 mg/g at the highest temperature (318 K). Brilliant Blue G biosorption increased for both materials and at pH 11 values reached 149 mg/g on IRA-400 Cl resin/A. campestris and 142 mg/g on IRA-4200 Cl resin/A. campestris. The characterization of adsorbents was done by scanning electron microscopy, element detection X-ray and Fourier transform infrared spectroscopy. The adsorption isotherms were examined for the biosorption process. The Harkins–Jura isotherm shows better fit than the other isotherms for IRA-4200 Cl resin/A. campestris, and the Freundlich isotherm is a better fit in the temperature range studied than the other isotherms for IRA-400 Cl resin/A. campestris biocomposite. Thermodynamic values such as enthalpy, change in entropy and Gibbs free energy were measured, and the biosorption process was found to be spontaneous and endothermic. As a result, IRA-400 Cl resin/A. campestris is a suitable biosorbent and has more typical proximity than IRA-4200 Cl resin/A. campestris biocomposite for biosorption of Brilliant Blue G from aqueous solutions.

一些介质参数对Amberlite树脂/姬松茸吸附艳蓝G的生物吸附的影响

在这项研究中,使用了两种生物复合材料,即Amberlite IRA-400 Cl树脂/ A。campestris和Amberlite 4200 Cl树脂/ A。campestris,来从水溶液中吸附亮蓝G。通过使用分批系统评估染料的生物吸附。另外,确定了培养基的一些物理化学和动力学参数如pH,温度,接触时间和初始浓度的影响。在此研究中,pH(3-11),吸附剂剂量(0.3 g),初始染料浓度(10-150 mg L -1),温度(298-318 K)和接触时间(10-95分钟)进行了研究。在第95分钟内,在最高温度(318 K)下,生物吸附量最高达到137.18 mg / g。马斯亮蓝G吸附增加了对两种材料和在pH 11个值达到149毫克上IRA-400氯树脂/ /克A.油菜和142毫克/克上IRA-4200氯树脂/ A.油菜。通过扫描电子显微镜,元素检测X射线和傅立叶变换红外光谱对吸附剂进行表征。检查吸附等温线的生物吸附过程。与IRA-4200 Cl树脂/ A. campestris的其他等温线相比,Harkins-Jura等温线显示出更好的拟合度,并且Freundlich等温线在研究的温度范围内比IRA-400 Cl树脂/ A. campestris生物复合材料的其他等温线更合适。测量了焓,熵变和吉布斯自由能等热力学值,发现生物吸附过程是自发的并且是吸热的。因此,IRA-400 Cl树脂/樟脑草是一种合适的生物吸附剂,并且比IRA-4200 Cl树脂/樟脑草生物复合物更能从水溶液中吸附亮蓝G。
