Abstract

Selective sorption of lead, cadmium, and nickel ions on recycled waste porous glass beads was investigated. Single-metal equilibrations were carried out in demineralized water and ternary metal equilibrations were carried out in demi- and tap water. Freundlich isotherm gave a good correlation of the experimental data. Maximum metal retention (qmax) in single-ion solutions were 18.66 mg= gRPWG (0.090 mmol=gRPWG), 4.83mg=gRPWG (0.043 mmol=gRPWG), 4.00mg=gRPWG (0.068 mmol=gRPWG), respectively, for Pbþ2, Cdþ2, and Niþ2, and lower figures were in the case of ternary systems: 13.50 mg=gRPWG(0.065 mmol=gRPWG), 2.23 (0.020 mmol= gRPWG), 2.05 mg=gRPWG(0.034 mmol=gRPWG), respectively, for Pbþ2, Cdþ2, and Niþ2, with further drastic reduction in tap water. Metal exhausted beads were used as thermal insulators in cement mortars, minimizing their potential impact in the environment.
