Background and Aim: Availability and low cost of date stones make them useful as raw material in the preparation of activated carbon. Cyanide, because of its toxicity for humans and aquatic organisms, is one of the most important health problems. The aim of the present study was to evaluate cyanide removal from aqueous solutions and determine influencing parameters in its adsorption into activa...
Background: One of the possible carcinogenic substances found in foods is Acrylamide (AA). This study aims to combine and innovate sea grapes (Caulerpa racemosa) extract with activated carbon into paper towels that can absorb AA levels in fried foods. Methods: The paper towel was created with composition of activated carbon: sea grapes extract: paper pulp using following formula: F0=0:0:100; F...
Background and Objective: Reactive dyes are the newest dyes in textile industry. They may cause environmental problems. The aim of this study was to remove Reactive Black 5 (RB5) in aqueous solutions with activated carbon that was made from grape wood. Materials and Methods: The activated carbon was synthesized by potassium carbonate with impragnation ratios of 1:0.25 at different temperatures...

in the present study, an indigenous medicinal plant, tridax procumbens (asteraceae) was used as bioadsorbent for the removal of cr (iii) ions from synthetic wastewater and the method was also applied for real sample analysis. the biosorption of cr (iii) was a two-stage batch reactor process. in the first stage, raw biomaterial was used to the conversion of cr (vi) into cr (iii). the amount of t...
Introduction: There are different methods for removal of cadmium from aqueous solutions. Adsorption based methods are among the bests. One of the most important aspects for adsorption techniques is the availability of an accessible and economical adsorbent. This study aims to investigate cadmium removal from aqueous solutions by walnuts shell waste. Materials and Methods: Walnut Shell (WS) was...
The aim of the study is to improve removal of trace organic contaminants dissolved in activated sludge by the process of filtration with membrane bioreactor combined with modified activated carbon, for a maximum removal of organic compounds characterized by low molecular weight. Special treatment was conducted in laboratory on activated carbon. Tow reaction parameters: the pH of aqueous middle ...
