Mechanism of Indigo carmine dye adsorption on palm wood cellulose activated carbon (PWCAC) was studied. The use of low cost ecofriendly adsorbent has been investigated as an ideal alternative to the current expensive methods of removing dye from aqueous solution. The study is done by batch adsorption techniques. The quantitative adsorption kinetic and equilibrium parameter for indigo carmine dy...

Discharge of dye effluents into the natural streams may be toxic to the aquatic lives as well as human being. In the present studies, zeolite was synthesized from coal fly ash by alkaline hydrothermal treatment and mixed with magnetite nanoparticles in suspension to produce zeolite-iron oxide magnetic nanocomposite. It was used as adsorbent for the removal of malachite green dye from aqueous so...

background: the rapid increase in agricultural and industrial development has made heavy metal pollution a serious environmental problem and public health threat; therefore, removal of heavy metals from water is important. the current study prepared dnph@sds@fe3o4 nanoparticles as a novel and effective adsorbent for removal of hg(ii) ions from an aqueous solution. methods: a selective adsorbent...

Activated carbon prepared from coir pith (ZnCPC) using ZnCl2 was investigated to find the feasibility of its application for removal of 2,4–dichlorophenol (2,4-DCP) in aqueous solution through adsorption process. Batch mode kinetics and isotherm studies were carried out to evaluate the effects of contact time, initial concentration, adsorbent dose, pH, and temperature. Lagergren, Second order, ...

Carbon slurry, dried in open air, has been used as an adsorbent material for the removal of nickel(II) from aqueous solutions at different experimental conditions in batch adsorption technique. The time required to attain equilibrium was found to be 50 minutes. The effects of initial concentration of Ni(II), particle size of adsorbent, adsorbent dose, temperature and pH on removal of nickel(II)...

Acacia polycantha frass (APF) generated by boring activity of Ambrosia beetles was investigated using a batch technique for its potential to adsorb Cr(III) ions from aqueous solution. Studies were carried out to determine the effect of pH, adsorbent dose, and KBr concentration on the sorption behavior Cr(III) on the adsorbent. The adsorption process was found to be highly dependent on solution ...

Nickel ferrite-polyaniline nanocomposite has been prepared and characterized using different techniques. The prepared nanocomposite is used as an adsorbent for the removal of arsenic from aqueous solution of sodium arsenite. The effect of temperature on the equilibrium adsorption of As(III) from aqueous solution on nanocomposite has been investigated. Effect of pH (2-12), contact time (0-70 min...

Activated carbons are extremely versatile adsorbents for major industrial significance, especially for metal ions recovery from wastewaters. In this study, the activated carbon prepared from the hard shell of apricot stones, an agricultural solid, which was used for the gold recovery from gold-plating wastewater is investigated. Activated carbon was produced by chemical activation with phosphor...

In this experimental data article, a novel biomaterial was provided from Malva sylvestris and characterized its properties using various instrumental techniques. The operating parameters consisted of pH and adsorbent dose on Hg(2+) adsorption from aqueous solution using M. sylvestris powder (MSP) were compared with charcoal tablet powder (CTP), a medicinal drug. The data acquired showed that M....

This study was focused on nettle ash as an alternative adsorbent for the removal of nickel (II) and cadmium (II) from wastewater. Batch experiments were conducted to determine the factors affecting adsorption of nickel (II) and cadmium (II). The adsorption process is affected by various parameters such as contact time, solution pH and adsorbent dose. The optimum pH required for maximum adsorpti...
