Backgrounds and Objectives: Treatment of colored wastewater is one of the important challenges of environmental engineers. Adsorption process is a key option for removal of organic matter from wastewater. The aim of present work was to investigate pumice stone as an adsorbent for removal of Acid Black 1 from aqueous solution.Materials and Methods: Removal of Acid Black 1 by pumice stone was inv...
In this study, the Acid Black 1 dye containing effluent collected from a dyeing unit was examined with the alginate extracted from the marine brown algae, Sargassum sp. for its removal. Batch experiments were carried out using standard Jar test apparatus. Fourier Transform InfraRed (FT-IR) Spectroscopy and Scanning Electron Microscopy (SEM) techniques were used to characterize the raw algin...
Background and Objective: Acid Black 1 dye due to the presence of benzene ring, toxicity, mutagenicity, carcinogenicity and non-degradability is one of the major dangers for human health and environment especially aquatic life. Hence, the removal of these compounds from polluted water and wastewater has been considered. This study has been investigated the removal of acid black1 azo dye f...
Background and purpose: The aim of this study was to investigate the efficiency of Fe3O4 nanoparticles synthesized by the chemical co-precipitation method for removal of black acid 1 from aquatic solutions. Materials and methods: In an experimental study, the Fe3O4 nanoparticle was synthesized by the chemical co-precipitation method using Fe+2 and Fe+3 solution in the presence of N2. The eff...
Dyes are widely used in various industries most of them are not readily biodegradable and are consisted of number of toxic, mutagenic, and carcinogenic compounds. Therefore, it is essential to remove them from effluent before their discharge to the environment. The objective of this investigation was to synthesize copper oxide (CuO) doped zinc oxide (ZnO) nanoparticles under mild hydrothermal c...
SBA-15 grafted with N-(4-(trimethylsilyl) butyl)-9H-fluorene-9-amine was synthesized by a simplestrategy and applied to removal of Acid Red 33 and Acid Black 194 from aqueous solutions. SBA-15 was synthesized and Functionalized according to procedure in the literature. Fluorenefunctionalized SBA-15 was showed the BET surface area 200 m2g-1 and pore diameter 4.2 nm,based on adsorption-desorption...
Background and purpose: The control of environmental pollution especially the pollution of water resources is one of the main challenges of researchers throughout the world. So, this study aimed to investigate the efficiency of reactive black 5 dye removal from aqueous solutions by adsorption onto activated carbon of grape seed. Materials and Methods: At first, the grape seed adsorbents were p...
Background and Objectives: The development a low-cost and high efficiency water treatment technology to decolorize the organic dye effluents is desirable due to overwhelming discharge of organic synthetic dyes into the natural water cycle during the dying process. In this study, the decolorization of Acid Black 26, as the model organic contaminant, was investigated using immobilized nano-sized ...
Background & Aims of the Study: Discharge of industrial wastewater to the environment has harmful effects. Textile industry is one of the industries that burdens pollutants to the environment. So the wastewater of these industries must be treated before discharging into the environment. Various methods for removing industrial pollutants have been investigated. Among them, AOPs have attracted mu...
decolorization of aqueous solutions containing ionic dyes (reactive blue 19 and acid black 172) by a tfc commercial polyamide nanofilter (nf) in a spiral wound configuration was studied. the effect of operating parameters including feed concentration (60-180 mg/l), pressure (0.5-1.1 mpa) and ph (6-10) on dye removal efficiency was evaluated. the response surface method (rsm) was utilized for th...
