Unreported graft copolymer of Meth Acrylamide (MAam) and our previously prepared and fully characterized chitosan nanoparticles (CNPs) as a starting substrate has been synthesized under nitrogen atmosphere using potassium chromate /mandelic acid as unique redox pair. This was done to see the impact of both CNPs with respect to well-dispersed nano sized particles, large surface areas, biodegradability and reactivity, MAam as highly reactive nitrogen containing monomer and the aforementioned novel redox pair with respect to a notable reduction in polymerization temperature for enhancing the graft yield %. The effect of reaction conditions on the graft yield % has been deliberated with respect to CNPs, MAam, potassium chromate, mandelic and sulphuric acids concentration in addition to polymerization time and temperature. The resultant copolymer has been characterized by FTIR spectroscopy and thermo gravimetric analysis. The results obtained reflect the following findings for the resultant copolymers in comparison with CNPs counterpart; (a) higher thermal stability (b) higher graft yield % obtained when [CNPs] 1.0 g, [potassium chromate] 100 mmol/l, [Mandeic acid], 80 mmol/l, [suphuric acid], 100 mmol/l, [MAam], 150% bows, reaction time, 120 min., and reaction temperature, 45 °C were used, (c) higher mercury ions scavenging activity and % removal when different dosage and extent of grafting of the copolymer are used up to the level required for industrial application, (d) recovered by washing the mercury ions from the complex with weak acid 1 N HNO₃ (pH 2) and its metal-binding activity was slightly bargain by this process, and (e) a preliminary mechanism representing all occasions that occur during the polymerization reaction has been projected.
