Adsorption of Malachite Green and Alizarin Red S Dyes Using Fe-BTC Metal Organic Framework as Adsorbent

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 ...

Metal-organic framework materials as nano photocatalyst

Photocatalytic degradation of toxic organic compound in water, soil and air by semiconductor catalysts such as TiO2 and ZnO have received much attention over the last two decades. However, the low quantum yield, easy agglomeration and difficult post-separation of these inorganic catalysts limit their application for large-scale applications. Metal-organic frameworks (MOFs) are the latest class ...

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

High-performance adsorption and separation of anionic dyes in water using a chemically stable graphene-like metal-organic framework.

A highly stable graphene-like metal-organic framework (BUC-17) was prepared and used as an adsorbent to carry out the adsorption of anionic dyes from simulated wastewater, which exhibited excellent adsorption performance, particularly towards Congo red (CR) up to 4923.7 mg g-1 at room temperature. It was used to fix a SPE column to conduct rapid separation of anionic dyes from an organic dye ma...
