Removal of heavy metal ions from wastewater by chemically modified plant wastes as adsorbents: A review
TL;DR: In this review, an extensive list of plant wastes as adsorbents including rice husks, spent grain, sawdust, sugarcane bagasse, fruit wastes, weeds and others has been compiled and some of the treated adsorbent show good adsorption capacities.
Journal ArticleDOI
Cationic and anionic dye adsorption by agricultural solid wastes: A comprehensive review
TL;DR: In this paper, the use of agricultural solid wastes to remove two classes of dye, cationic and anionic dyes, was discussed and a simple comparison among cationi-and anionic dye adsorption by the same adsorbent was made, thus possibly opening the door for a better understanding of the dye-classified adaption process.
Journal ArticleDOI
Cr(VI) and Cr(III) removal from aqueous solution by raw and modified lignocellulosic materials: a review.
TL;DR: This study is a review of the recent literature on the use of natural and modified lignocellulosic residues for Cr adsorption and finds that many by-products of agriculture have proved to be suitable low cost adsorbents for Cr(VI) and Cr(III) removal from water.
Journal ArticleDOI
Removal of Hexavalent Chromium-Contaminated Water and Wastewater: A Review
TL;DR: A survey of removal techniques for Cr(VI)-contaminated aqueous solutions is given in this article, with a particular focus on adsorption, membrane filtration, ion exchange, and electrochemical treatment methods.
Journal ArticleDOI
Water purification by using Adsorbents: A Review
TL;DR: In this article, a large number of solid adsorbents such as Natural Adsorbents, Agricultural Wastes, Industrial wastes, Biomass, Nanoadsorbents: Carbon based nanomaterials, Nobel metal based nano-materials, Metal oxide based nanomorphs, Spinel ferrite-based nanomological material, Nanocomposites, Dendritic polymers; Geopolymer cement have been discussed for the removal of different pollutants from waste water.

The kinetics of sorption of divalent metal ions onto sphagnum moss peat
Yuh-Shan Ho,Gordon McKay +1 more
TL;DR: In this paper, a pseudo-second order rate equation describing the kinetics of sorption of divalent metal ions onto sphagnum moss peat at different initial metal ion concentrations and peat doses has been developed.
Journal ArticleDOI
Use of Detergents in the Analysis of Fibrous Feeds. II. A Rapid Method for the Determination of Fiber and Lignin
TL;DR: The acid-detergent fiber method (ADF) as mentioned in this paper is a fiber method based on cetyl trimethylammonium bromide to dissolve proteins in acid solution.
Journal ArticleDOI
The removal of heavy metal cations by natural zeolites.
TL;DR: The results show that natural zeolites hold great potential to remove cationic heavy metal species from industrial wastewater.
Journal ArticleDOI
Single- and multi-component adsorption of cadmium and zinc using activated carbon derived from bagasse--an agricultural waste.
Dinesh Mohan,Kunwar P. Singh +1 more
TL;DR: Activated carbon derived from bagasse, an agricultural waste material, has been investigated as a replacement for the current expensive methods of removing heavy metals from wastewater and it was concluded that the adsorption occurs through a film diffusion mechanism at low as well as at higher concentrations.

Selective adsorption of chromium(VI) in industrial wastewater using low-cost abundantly available adsorbents
TL;DR: In this article, the removal of poisonous Cr(VI) from industrial wastewater by different low-cost abundant adsorbents was investigated, including wool, olive cake, sawdust, pine needles, almond shells, cactus leaves and charcoal were used at different adsorbent/metal ion ratios.
