Abstract

A new modified magnetic Graphene Oxide with Chitosan and Cysteine was
synthesized for removing Pb2+ ions from aqueous solution. The properties of this
adsorbent were characterized by Field Emission Scanning Electron Microscopy (FESEM),
Vibrating Sample Magnetometer (VSM) and Energy Dispersive Analysis System
of X-ray (EDAX). Physicochemical parameters such as effect of pH, contact time,
adsorbent dosage and initial concentration of Pb 2+ was also studied. The results showed
that the maximum capacity of absorbent in Lead ions adsorption (at Equilibrium
concentration of 120 ppm) occurred at pHOptimum= 5.75, tOptimum= 30 min and
adsorbent 85.4 mg/g dosage=0.1 gr. Maximum empirical adsorption capacity (qmax) was
calculated 85.4 mg/g. The thermodynamic parameters (ΔHᵒ, ΔGᵒ and ΔSᵒ) showed that
the adsorption process of Pb 2+ on modified magnetic Graphene Oxide with Chitosan
and Cysteine was endothermic and spontaneous. Removal percentage was reduced to
15% after five stages of Sorption/desorption studies. So, modified magnetic Graphene
Oxide with Chitosan and Cysteine can be used as a complementary process for removal
of Pb2+ ions from water and wastewater.
