Graphene Oxide (GO) based adsorbents have attracted much attention from researchers because there been many reports that they are effective for removing dyes aqueous environments. That is GO has good mechanical, electrical, optical and chemical properties, so graphene its derivatives, such as oxide, used in various applications the field of environmental management. Modifying into nano size an ...

The absorption of an oral 2-g dose of paracetamol was markedly reduced by the simultaneous oral administration of either activated charcoal or cholestyramine but was only slightly reduced when the adsorbents were given 60 minutes after the paracetamol. Since the absorption of a larger dose of the drug will probably be slow, the administration of adsorbents may be of value even when delayed seve...

Highlight Research New method to synthesis nano chitosan from Vannamei shrimp with high Deacetylation Degree Nano can adsorb heavy metal Fe up 81.35% Shrimp shells as an alternative adsorbents for Abstract cultivation produces wastes in several forms, including the molting process. shell waste be used a source of chitosan. Many researches have various applications, one which is pollution. This ...

According to a 1999 study by the National Academy of Sciences, arsenic in drinking water can cause several types of cancer, harm the central and peripheral nervous systems, cause serious skin problems, cause birth defects and reproductive problems. The USEPA published a Final Arsenic Rule in the Federal Register that established a revised Maximum Contaminant Level (MCL) for Arsenic of 10μg/L (U...

Hybrid materials using a macroporous sponge and spherical microporous adsorbents have been developed for an effective rapid pretreatment of water samples. Various adsorbents, including methacrylate series, divinylbenzene (DVB), and graphite particles, were utilized for hybridization with a macroporous sponge consisting of polyethylene and polyvinyl acetate, EVA resin. Both the EVA resin and eac...

Population growth, coupled with industrialization and urbanization, has resulted in an increasing demand for water thus leading to water crisis and serious consequences on the environment. The effluent stream released from the industries mainly comprises of hazardous chemicals and heavy metal ions. Chromium is abundant in nature and has a dominant presence in most of the effluent streams as com...

The aim of this work was to correlate the textural and chemical features of carbonaceous adsorbents with the adsorption capacity of naphthalene from aqueous phase, at the concentration in which this compound is usually found in wastewater from coke ovens. The study reveals that the adsorption capacity in different carbon materials depends not only on the textural characteristics of the material...

The use of mixed self-assembled monolayers, combining hydrophobic co-adsorbents with the sensitizer, has been demonstrated to enhance the efficiency of dye-sensitized solar cells (DSCs). Herein, the influence of the anchoring groups of the co-adsorbents on the performance of the DSCs is carefully examined by selecting two model molecules: neohexyl phosphonic acid (NHOOP) and bis-(3,3-dimethyl-b...

A comprehensive synthetic approach is applied here to localize the continuous antigenic sites of the beta-chain of haemoglobin. The approach was based on the synthesis and purification of the following consecutive 15-residue peptides (each overlapping by five residues at both ends with the peptides preceding it and following it in the sequence): 1-15, 11-25 etc. Quantitative radiometric titrati...

Adsorption and desorption studies on different types of adsorbents, including natural materials such as teak tree bark powder, rice husk, natural bentonite, different algae like Ecklonia maxima, Escherichia coli, Ascophyllum nodasum, Rhizopus nigricans, Cladophora fascicularis, goethite and soils of three nuclear power plant and artificial materials such as Fe oxide-coated sand, goethite pretre...
