Amino-alcohol functionalized porous polymer coupled with chromium hydroxide nanoparticles for efficient Cd(ii) adsorption from aqueous solutions.

Cadmium is one of the most hazardous heavy metal contaminants, and it is usually abundant in the wastewater released from paint and pigment industries. Such effluents urgently need to be treated before their proper reuse for various industrial and agricultural purposes. Therefore, in this study, the process of Cd(ii) ion adsorption from waste aqueous-solutions was investigated using polystyrene (PS), ethanolamine-modified polystyrene (EA-PS), and chromium hydroxide-impregnated ethanolamine-modified polystyrene (Cr@EA-PS) as new effective sorbents.

Conversion of carbon black recovered from waste tires into activated carbon chemical/microwave methods for efficient removal of heavy metal ions from wastewater.

In this research study, recovered carbon black (rCB) was obtained pyrolysis of waste tires. The obtained rCB was then converted into activated carbon species through both chemical treatment and microwave coupled with chemical treatment as a two-step activation process. The activated carbon obtained from chemical activation was denoted as C-AC, while that obtained from exposure to microwave followed by chemical activation was labeled as MC-AC.

Cadmium and iron removal from phosphoric acid using commercial resins for purification purpose.

Three commercial resins bearing sulfonic, amino phosphonic, or phosphonic/sulfonic reactive groups have been tested for the removal of iron and cadmium from phosphoric acid solutions. The sorption properties are compared for different experimental conditions such as sorbent dosage (0.5-2.
