چکیده
Abstract Unreported graft copolymer of Meth Acrylamide (MAam) and our previously prepared fully characterized chitosan nanoparticles (CNPs) as a starting substrate has been synthesized under nitrogen atmosphere using potassium chromate /mandelic acid unique redox pair. This was done to see the impact both CNPs with respect well-dispersed nano sized particles, large surface areas, biodegradability reactivity, MAam highly reactive containing monomer aforementioned novel pair notable reduction in polymerization temperature for enhancing yield %. The effect reaction conditions on % deliberated CNPs, MAam, chromate, mandelic sulphuric acids concentration addition time temperature. resultant by FTIR spectroscopy thermo gravimetric analysis. results obtained reflect following findings copolymers comparison counterpart; (a) higher thermal stability (b) when [CNPs] 1.0 g, [potassium chromate] 100 mmol/l, [Mandeic acid], 80 [suphuric [MAam], 150% bows, time, 120 min., temperature, 45 °C were used, (c) mercury ions scavenging activity removal different dosage extent grafting are used up level required industrial application, (d) recovered washing from complex weak 1 N HNO 3 (pH 2) its metal-binding slightly bargain this process, (e) preliminary mechanism representing all occasions that occur during projected.
