removal of hexavalent chromium (vi) from aqueous solutions using surface modified nanozeolite a
chromium (vi) adsorption behavior and capacity by surface modified nanozeolite a has been investigated. surface modification was performed and the morphology of modified and unmodified nanozeolite was studied using scanning electron microscope (sem) and transmission electron microscope (tem). adsorption isotherms were studied under different conditions (ph, adsorbent dose, adsorbate concentrati...
متن کاملHumic acid removal from aqueous solutions by peroxi-electrocoagulation process
Background: Natural organic matter is the cause of many problems associated with water treatment such as the presence of disinfection by-products (DBPs) and membrane fouling during water filtration. In this study, the performance of the peroxi-electrocoagulation process (PEP) was investigated for the removal of humic acids (HAs) from aqueous solutions. Methods: PEP was carried out for the remov...
متن کاملRemoval of methylene blue from aqueous solutions using modified clay
Introduction: Discharging of industrial colored wastewaters especially into aqueous environments can cause adverse effects on aquatic life due to their toxic natures. In this study, montmorillonite modified by hexadecyltrimethyl ammonium bromide (HDTMA-Mt) was used for the adsorption of methylene blue (MB). Materials and Methods: The influence of surfactant loading rate, contact time, pH, adso...
متن کاملApplication of modified bentonite using sulfuric acid for the removal of hexavalent chromium from aqueous solutions
Background: Environmental contamination by chromium (Cr) has become an important issue due to its adverse effects on human health and environment. This study was done to evaluate the application of modified bentonite using sulfuric acid as an adsorbent in the removal of hexavalent Cr from aqueous solution. Methods: Adsorbent features were determined using x-ray diffraction (XRD), fourier transf...
متن کاملCadmium Removal from Aqueous Solutions Using Saxaul Tree Ash
Cadmium can be found in wastewater in high concentrations and can cause dangerous effect on aqueous environment and human health. At present, many methods have been used to heavy metals removal. Among this clean up techniques, adsorption techniques by using low-cost adsorbent are more considerable. In this study, batch adsorption experiments were conducted for removal of cadmium ions from a...
