It is now recognized that adsorption using low-cost adsorbents is an effective and economic method for water decontamination. Chitosan is derived by deacetylation of the naturally occurring biopolymer chitin which is the second most abundant polysaccharide in the world after cellulose. In this study, the capacity of the chitosan nanoparticles was studied for the removal of the anionic Congo red...

The adsorption and removal of congo red from an aqueous solution by iron oxide nanoparticles (IONPs) coated with cetyltrimethylammonium bromide (CTAB) as adsorbent was reported. The novel magnetic separation was quite efficient for the adsorption and desorption of congo red. The effect of temperature, pH of aqueous medium, and interfering ions on the recovery process were also investigated. The...

Advance regeneration in 52 mature mixed-oak stands was analyzed and described. Red maple (Acer rubrum L.) was the most abundant species in the study area. Among oak (Quercus) species, northern red oak (Q. rubra L.) was the most abundant within the Allegheny Plateau physiographic province, whereas chestnut oak (Q. montana L.) was the most abundant within the Ridge and Valley physiographic provin...

We treated 2,4,6-trinitrotoluene (TNT) red water from the Chinese explosive industry with activated coke (AC) from lignite. Since the composition of TNT red water was very complicated, chemical oxygen demand (COD) was used as the index for evaluating treatment efficiency. This study focused on sorption kinetics and equilibrium sorption isotherms of AC for the removal of COD from TNT red water, ...

The removal kinetics and mechanism of alizarin red-s dye, adsorptions on coconut shell activated carbon [CSAC] is studied. The use of low cost ecofriendly adsorbent has been investigated as an ideal alternative to the current expensive methods of removing the dye from aqueous solution. The adsorption removal of Alizarin Red-S dye on CSAC was investigated using batch adsorption technique. The di...

abstract background: dyes are visible materials and are considered as one of the hazardous components that make up the industrial waste. dye compounds in natural water, even in very low concentrations, will lead to environmental problems. azo dyes are compounds with one or more –n=n– groups and are used in textile industry. because of its low price, solubility, and stability, azo dyes are widel...

The utilization of less expensive and more effective adsorbents derived from a variety basic materials has been investigated. research aimed to investigate the feasibility employing waste paper as adsorbent remove cresol red (CR) dye wastewater through adsorption mechanism. Langmuir, Jovanovic, Freundlich model were observed for isotherms models, while pseudo-first-order pseudo-second-order exa...
