Application 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 کاملBiosorption of hexavalent Chromium by the agricultural wastes of the cotton and barberry plants
Hexavalent chromium, a highly toxic metal ion employed in industrial activities, is considered as a first priority pollutant. In this study, the capsule walls of the boll of cotton (cotton waste, CW) and the waste obtained from pruning barberry bushes (barberry waste, BW) were investigated as cheap and locally available adsorbents for Cr (VI) removal. The adsorption behavior, equilibrium, and k...
متن کاملAnalysis of Carbonated Biosorbents Application in Heavy Metal Removal from Synthetic Wastewater
Purpose: This study aimed to analyze the effects of removal of hexavalent Chromium using carbonated almond green hulls. In the present study, derived carbon fromalmond green hulls of zonal district of Iran were used to remove hexavalent Chromium from Synthetic wastewater. Materials and Methods: The effects of pH (2-10), Adsorbent dose (2-24 g/L), Cr (VI) concentration (10-100 mg/L), Contact...
متن کاملبررسی حذف کروم ششظرفیتی از محلولهای آبی با استفاده از کربن عاملدار تهیهشده از پوسته برنج
Background and Aim: Hexavalent chromium is a heavy metal with harmful effects on surface and ground water. Its removal from contaminated water and waste water has received great interest in recent years. This study aimed to evaluate the absorption of hexavalent chromium from aquatic environments using functionalized carbon produced from rice husk as an inexpensive and biological adsorbent. Mat...
متن کاملHexavalent chromium removal from a simulated wastewater using Fe(II) modified bentonite
Background and Objective: Hexavalent chromium is reported to be highly toxic, mutagenic and carcinogenic; hence treatment of water and wastewater contaminated with this element by low-cost and environmentally friendly methods is of great importance. Therefore the aim of present study was to evaluate the efficiency of Fe(II) modified bentonite for hexavalent chromium removal from a simulated was...
