Effective removal of nickel(II) and zinc(II) in mono-compound and binary systems from aqueous solutions by application of alginate-based materials

In the present study, beads of alginate, alginate-biuret and alginate-urea, were synthesised for removal Ni(II) Zn(II) metal ions from aqueous solution (in single in bimetallic component solution). The properties sorbents investigated by pHpcz, ESEM-EDX ESEM. modelling experimental data demonstrate that PSORE equation fits well kinetic profiles, while Langmuir also Sips models correspond to results sorption isotherms (heterogeneous surface). Also, spontaneous process endothermic nature was demonstrated thermodynamic study. maximum capacity 3.22, 4.73 8.53 mmol g?1 found respectively, case it 6.77, 6.97 7.14 Zn(II). It at 0.3 L?1 concentration, selectively adsorbed concentrated/enriched but alginate almost same amount solution, study selectivity coefficients (KS) shows alginate-urea is a selective sorbent ions. Therefore, two functionalised polysaccharides do not show harmony front two-chemical species, thus, giving possibility their use as adsorbents solutions containing these elements can be used applications different interest.
