Effectiveness of termite hill as an economic adsorbent for the adsorption of alizarin red dye

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 ...

Adsorption of Alizarin Red Dye from Aqueous Solution on an Activated Charcoal

The activated charcoal was used for the removal of alizarin red dye from aqueous solution. Different parameters such as effect of contact time, initial dye concentration and pH were investigated. It was observed from the concentration study that the amount of dye adsorbed per unit mass of the adsorbent increased with increase in dye concentration. The pH study presented that the adsorption of d...

Adsorption Capacity of the as-Synthetic Graphene Oxide for the Removal of Alizarin Red S Dye from Aqueous Solution

This research was aimed to study the adsorption of Alizarin Red S (ARS) dye using graphene oxide (GO) as an adsorbent compared with bare graphite powder (BGP). For optimum conditions, the effects of the initial concentration of ARS, solution pH, adsorbent dosage, and contact time were investigated in detail. The optimum conditions for this work were consisted of 350 mg/L initial concentration o...
