تأثیر معالجة الماء الملوث بالصبغة العضویة على إنبات بذور القمح الصلب

Abstract

This study aims to use natural clay from Mesila state as an adsorbent to remove an organic pollutant, namely Safranin-O dye from aqueous solutions and to study its adsorption capacity as well as study the factors affecting adsorption. The physicochemical and mineral properties of clay were studied using XRD, FTIR, SEM/EDAX, XPS after treating the clay physically and chemically. For 1 hour at a temperature of 50°C. The yield of SAF-O stain removal. In addition, the modeling results showed that the Longmire isotherm was more suitable with a regression coefficient, and the maximum amount adsorbed according to the Longmire model. As for the kinetic modeling, its results showed that the adsorption kinetics followed a quasi￾second-order model with a regression coefficient equal to 1. The slurry adsorption efficiency was improved by modifying it with alkyl salt, as we obtained a maximum adsorbent using instead mass used in natural clay.
