Adsorptive Removal of Reactive Black 5 from Aqueous Solution using Chitin Prepared from Shrimp Shells

adsorption of zn (ii) from aqueous solution by using chitin extracted from shrimp shells

background chitin and its derivatives (chitosan) are natural biopolymer produced from crustacean shell, which due to their active functional groups such as amine and hydroxyl have high ability to absorb heavy metals from water and wastewater. the aim of this study was to investigate zinc removal from aqueous solutions by using chitin extracted from shrimp shells. material and methods to study t...

Removal of bromocresol green from aqueous solutions using chitin nanofibers

Synthesis and Performance Evaluation of Chitosan Prepared from Persian Gulf Shrimp Shell in Removal of Reactive Blue 29 Dye from Aqueous Solution (Isotherm, Thermodynamic and Kinetic Study)

This study was aimed to investigate the amount of reactive blue 29 (RB29) dye removal from aqueous solution by Chitosan extracted from Persian Gulf shrimp shell. The effect of parameters such as pH, the concentration of reactive blue 29 dye, contact time, and adsorbent dosage in dye removal was studied. Isotherm, Thermodynamics, and kinetics of adsorption process were also investigated. The...

Adsorptive Removal of Reactive Black 5 from Wastewater Using Bentonite Clay: Isotherms, Kinetics and Thermodynamics

The studies of the kinetics and isotherms adsorption of the Reactive Black 5 (RB5) onto bentonite clay were explored in a batch study in a laboratory. The maximum RB5 adsorption conditions of bentonite clay were optimized such as shaking speed (100 rpm), temperature (323 K), pH (10), contact time (40 min), initial dye concentration (170 mg·L−1), and particle size (177 μm). The adsorbent surface...

Adsorption of Zn (II) from aqueous solution by using chitin extraction from crustaceous shell

Removal of toxic heavy metals from wastewater is an important environmental challenge. In this Study, Zn (II) removal from aqueous solution by chitin extraction from crustaceous shells (shrimp and crab) was investigated. The biosorption studies were determined as a function of contact time, pH, initial metal concentration, and the amount of adsorbent. Adsorption of Zn (II) increased with decrea...
