Abstract

In this study, the removal performance of the Reactive Blue 19 (RB19) dye of the magnetized and non-magnetized industrial tomato solid waste (TW) from the aqueous medium was investigated. The properties of the prepared TW and magnetically modified TW (MTW) bio-sorbents were illuminated using XRD, BET, SEM, VSM, FT-IR and Boehm titration analysis techniques. The optimal conditions for sorption of RB19 by both sorbents were identified. The kinetics and equilibrium data of RB19 sorption by both sorbents were found to match the pseudo-second-order kinetic and Langmuir isotherm models, respectively, with high correlation coefficients. The maximum RB19 sorption capacity under the optimum conditions determined by TW and MTW was determined as 38.76 and 58.14 mg/g, respectively. Thermodynamic parameters calculated for RB19 sorption by both sorbents showed that the processes were spontaneous and exothermic.

摘要

在这项研究中，研究了活性蓝19（RB19）染料对磁性和非磁性工业番茄固体废物（TW）从水性介质中的去除性能。使用XRD，BET，SEM，VSM，FT-IR和Boehm滴定分析技术对制备的TW和磁性改性TW（MTW）生物吸附剂的性质进行了照明。确定了两种吸附剂吸附RB19的最佳条件。发现两种吸附剂吸附RB19的动力学和平衡数据分别与拟二阶动力学模型和Langmuir等温线模型匹配，并且相关系数较高。在TW和MTW确定的最佳条件下，最大RB19吸附容量分别为38.76和58.14 mg / g。
