Ficus religiosa bark an efficient adsorbent for Alizarin Red S dye: Equilibrium and kinetic analysis

Removal of Alizarin Red Dye Using Calcium Hydroxide as a Low-cost Adsorbent

Calcium ions have very strong affinity and binds effectively to alizarin red dye during staining of biomaterials. This promotes us to choose calcium hydroxide as a low cost adsorbent for the removal of alizarin red dye. Various parameters such as pH, concentration, dose of adsorbent, time, and temperature have been investigated. In addition, enthalpy, entropy, free energy and activation energy ...

Equilibrium Modeling and Kinetic Studies on the Adsorption of Basic Dye by a Low Cost Adsorbent

An agricultural waste and eco-friendly biosorbent i.e. rice husk has been used as a cheap adsorbentfor the removal of methylene blue dye from aqueous solutions. The physical properties of the developedadsorbent were characterized using FTIR. The study was realized using batch experiments. The effectsof contact time, pH, initial dye concentration, biosorbent dose and temperature were investigate...

Synthesis of Nano-Titanium Tannate as an adsorbent for Crystal Violet Dye, Kinetic and Equilibrium Isotherm Studies

The purpose of this study was to prepare nano-titanium tannate complex (TTC) and to investigate its adsorption capacity for removal of cationic dyes such as crystal violet (CV) dye. The morphology and the main elements of TTC adsorbent were characterized by scanning electron microscopy (SEM-EDS), while its crystal structure was characterized by X-ray diffraction (XRD). Also, FT-IR spectroscopy ...

Electrocoagulation removal of anthraquinone dye Alizarin Red S from aqueous solution using aluminum electrodes:

Electrocoagulation (EC) was used for the removal of anthraquinone dye, Alizarin Red S (ARS) from aqueous solution. The process was carried out in a batch electrochemical cell with Al electrodes in a monopolar connection. The effects of some important parameters such as current density, pH, temperature and initial dye concentration, on the process were investigated. Equilibrium was attained afte...
