Background and purpose: Phenol and its derivatives are used as raw material in many chemical, pharmaceutical and petrochemical industries. It is classified as priority pollutant, due to its high toxicity. In this study, the magnetic activated carbon nano-composite was used for quick removal of phenol. Materials and methods: The activated carbon was modified by magnetic nano-particles....
Organic fraction of solid waste, which upon degradation produces foul smell and generates pathogens, if not properly managed. Composting is not a method of waste disposal but it is a method of waste recycling and used for agricultural purposes. An integrated approach of composting methodology was tested for municipal solid waste management. Solid waste first was composted and after 22 days, was...
a new, local agro-industrial waste was valorized by chemical treatment and tested for its ability to remove cationic dye from aqueous solution. tendu (diospyros melanoxylon) leaves refuse, a solid waste from bidi industry which caused disposal problem, was studied as a biosorbent. raw tendu waste (tlr), along with sulfuric acid carbonized tendu waste (tlr-cm) and tendu waste treated with dilute...
A procedure for preparation of semi-activated carbon fiber (SACF) without any treatment under high temperature was proposed. The first step of the procedure is coating of an inorganic fiber (E-glass fiber) by an adsorbent mixture including powder activated carbon, methyl cellulose and water. In this work a set of experiments was performed to attain appropriate adsorbent mixture for good quality...
This paper presents a systematic study of the surface chemistry, porous texture and adsorptive characteristics of prepared new activated carbon using Persian mesquite grain. Several techniques and methodologies such as, proximate analysis, N2 adsorption–desorption isotherms, scanning electron microscope (SEM), Fourier transform infrared spectroscopy(FT-IR), X-ray Diffraction (XRD), X-ray photoe...
جذب سطحی به عنوان یک فرآیند موثر، روش مناسبی در تصفیه نهایی فاضلابهای صنعتی حاوی مواد سمی می باشد. فنل : به عنوان یک ماده آلی سمی و خطرناک موجود در اکثر فاضلابهای صنعتی، باید مورد تصفیه قرار گیرد. تحقیق حاضر شامل بررسی کاربرد سه ماده کربن گرانولی فعال َaclکربن پوست بادامascو کربن پوست گردوwsc به عنوان جاذب جهت حذف فنل از آب و فاضلاب صنعتی آلوده به فنل می باشد استفاده از کربن پوست بادام و گردو در...
Background and purpose: Chromium hexavalent compounds are carcinogens that are found in groundwater as chromate and dichromate negative ions. The aim of this study was to remove Cr (VI) from water by activated carbon modified with cationic surfactant alkyl dimethyl benzyl ammonium chloride (Benzalkonium chloride). Materials and methods: In terms of the Critical Micelle Concentration (CMC) of...
A new activated carbon was produced from pulp and paper mill sludge as a low cost precursor via chemical activation by zinc chloride. The activated carbon was successfully used for the adsorption of phenol and two of its derivatives, i.e. 2-chlorophenol and 4-nitrophenol from aqueous solutions. The characterization of the prepared activated carbon demonstrated high textural properties for the s...
