role of activated carbon from natural adsorbent for removal of textile dyes: effect of ph, kinetic and adsorbent mass

in the present work, we have investigated the sorption efficiency of the treated activated carbon from walnut shell(acw) towards direct red 81 (dr81) and direct blue 71 (db71) for the removal from aqueous solution. thesorption study of acw at the solid-liquid interface was investigated using kinetic, sorption isotherms, ph effectand amount of adsorbent. experimental data were analyzed by langmu...

Investigation on the capability of Silkworm Pupa as a Natural Adsorbent for Removal of Dyes from Textile Effluent

Recently, use of naturally-occurring low-cost and harmless material for removal of trace contaminants from colored wastewater has attracted extensive attention. In this study, silkworm pupa has been used as a basic dye adsorbent. Adsorption capacity and isotherms have been assessed. Results show that adsorption isotherms can be expressed well by Langmuir equation. The effects of parameters such...

Acid Dyes Removal from textile wastewater using waste cotton activated carbon: Kinetic, isotherm, and thermodynamic studies

The present study aims at investigating the potential of activated carbon AC prepared from waste cotton fiber for the removal of Acid Dyes from aqueous solutions. The prepared activated carbon was characterized by pore structure analysis, Fourier transforms infrared spectroscopy FTIR. Batch adsorption studies were carried out and the effect of experimental parameters such as pH, initial dye con...

The Perlite-calcium Alginate-activated Carbon Composite as an Efficient Adsorbent for the Removal of Dyes from Aqueous Solutions

To remove dyes from wastewater, the perlite-calcium alginate–activated carbon (PCA) composite was prepared by a simple method. This composite was characterized by FTIR, XRD, SEM, and BET techniques. A high capacity of PCA was observed for the adsorption of some dyes such as methylene blue (MB) and methyl orange (MO) from aqueous solutions (1111 and 909 mg g-1). The best results were achieved at...

Removal of pollutant heterocyclic dyes from water with ZnO adsorbent

In this study, Copper oxide as a good and inexpensive adsorbent has been introduced and used for the removal of erythrosine and red carmoisine dyes from several water solutions successfully. The effect of various parameters such as pH, dye concentration, amount of adsorbent, contact time and temperature on removal processing was investigated. Adsorption isothermal data could be interpreted by t...
