cesium chromium processes

Determination of chromium and caesium in human

Caesium is a biologically important trace-element due to its relationship with potassium, as has been demonstrated in a variety of biochemical and physiological processes. The concentration of these elements was determined in cataractous lenses from fifty-one patients with senile cataract and has been correlated with age and sex.

Processes | Free Full-Text | Selective Cesium

For cesium recovery, general methods, solid adsorption, and solvent extraction, have been so far applied. Some extractants exhibit remarkable efficiency for cesium (I) extraction due to their specific macrocyclic structures [3,4,5], despite having some disadvantages such as the use of flammable and undesirable organic solvents. Metal ion adsorption either on the surface or inner of adsorbents from aqueous
