Static Adsorption of Sr2+ with Low Concentration by Granulated Ca-Alginate

Abstract

The adsorption of Sr 2+ from solution with low concentration onto dried Ca-alginate was investigated in batch system. The adsorption dynamics, thermodynamics and effects of pH on Sr 2+ sorption capacity were carried out and the energy parameters of adsorption were computed. The results show that the adsorption of Sr 2+ onto dried Ca-alginate was rapid and low temperature was in favour of adsorption. The adsorption was considered a spontaneous exothermic process. The capacity of adsorption reaches the maximum when pH was 7. The energy parameters and electronic property of system have discovered that the MM block has the best adsorptive effect of Sr 2+ in all three kinds of blocks.

Hard Carbon Derived From Different Precursors for Sodium Storage

“…Additionally, natural biomass typically incorporates heteroatoms, including nitrogen, fluorine, sulfur, boron, and so forth, which exert multifaceted influences on the characteristics of HCs derived from biomass. Abundant research suggests that heteroatom doping can boost the conductivity, defect quantity, or interlayer spacing of carbon materials, effectively augmenting the storage performance of sodium [51] …”
