title: Analysis of lead in beverage juice using mesoporous cadmium phosphate as a solid phase adsorbent.
abstract: Toxic heavy metals in beverages can seriously harm human health. In the present work, a facile and eco-friendly biosynthesis of mesoporous cadmium phosphate (MPCP), using bovine serum albumin (BSA), has been successfully developed. BSAs were used to regulate the nucleation and growth of cadmium phosphate; MPCP has been used for lead ions removal from juice beverage solution and it has very excellent adsorption property capacity for Pb(II). Its adsorption kinetics could be modelled by the pseudo second-order rate equation, and the thermodynamic parameters ΔG, ΔH and ΔS were - 5.95 kJ mol(-1), 15.08 kJ mol(-1), and 68.09 J K(-1)mol(-1), respectively. Therefore, the present research work has provided an effective way for lead ion removal in drinks, and the results suggest that MPCP might be used as a promising adsorbent with high efficiency for heavy metal ion uptake in the beverage industry.
