Development of titanium doped hydroxyapatite for efficient removal of radioactive strontium from contaminated water

Abstract

The present study explores the potential of hydroxyapatite (HA) and titanium-doped hydroxyapatite (Ti-HA) for the efficient removal of radioactive strontium (Sr-90) from contaminated water. Both the HA and Ti-HA were...

Efficient lead sorption by ammonium phosphomolybdate: experimental and density functional theory (DFT) studies

“…The value of the sorption intensity parameter (1/ n ) lies between 0 and 1, indicating the favorable sorption; additionally, the amount of sorbate sorbed per unit weight of sorbent also increases linearly with increasing the concentrations. 51 Moreover, the predicted sorption capacity (951.65 mg g −1 ) is in good agreement with the experimental sorption capacity (923.25 mg g −1 ) in the case of the Freundlich model.…”

“…If the difference between q cal and q exp is greater, higher χ 2 values will be obtained, and vice versa . The equation below gives the mathematical expression of the χ 2 test: 51 …”
