Synthesis and Characterization of Low-Cost Adsorbent and used for Alizarin Yellow GG and Alizarin Red S Dyes Removal from Aqueous Solutions

Removal of Alizarin Red and Purpurin from Aqueous Solutions Using Fe3O4 Magnetic Nanoparticles

The applicability of Fe3O4 nanoparticles (Fe3O4NPs) for removing alizarin and purpurin from aqueous solutions has been reported. The influence of nanoparticle dosage, pH of the sample solution, individual dye concentration, contact time between the sample and the adsorbent, temperature, and ionic strength of the sample solution were studied by perform...

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 ...

Red Reactive 2 Dye Removal from Aqueous Solutions by Pumice as a Low-Cost and Available Adsorbent

removal of alizarin red dye using calcium hydroxide as a low-cost adsorbent

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...
