Abstract
In this study ,some chalcones were prepared by using terphthaldehyde with ketone aromatic compound in basic surrounding (NaOH) ,These compounds was studied by infrared (IR) , Nuclear Magnetic Resonance (NMR) and (CHN). The prepared chalcon (1) (2,2')-3,3'-(1,4-phenylene) bis(1-pyridin-2-yl)prop-2-en-1-one) chalcon (2) (2,2')-3,3'-(1,4-phenylene) bis(1-pyridin-3-yl) prop-2-en-1-one) and chalcon (3) (2,2')-3,3'-(1,4-phenylene) bis(1-pyridin-4-yl)prop-2-en-1-one),These chalcones were supported on rigid polymer than foam and the produced chelating polymers were evaluated for their loading capacity towards (Pb2+,Ni2+,Cu2+,Cr3+, Cd2+, Co2+,Mn2+,Zn2+) ions ,Polymer (P3) show no response ,but polymers (P1,P2) showed no response toward (Mn2+ and Zn2+ ) ions, and low loading capacity towards (Cr3+ and Cd2+) ions, but the rest resins showed a good resins toward the rest ions (Pb2+,Ni2+,Cu2+,Co2+).The effect of treatment time and pH on the loading capacity of the resins were studied while other parameters ,like temperature ,weight of resin and metal ion concentration were kept constant. The results of max. loading capacity for Polymer(P1) were as: (Pb2+=9.5, Cu2+=8.9, Ni2+=8.8, Co2+=8.6). and the results of max. loading capacity for Polymer(P2) were as: (Pb2+=7.8, Cu2+=7.3, Ni2+=7.5, Co2+=7.0). The recovery of ions from resins (P1) and the regeneration of the resin were also studied using 3M HNO3 as an eluent. The %recovery of each ion from the studied resins are:- (Pb2+=74.6, Ni2+=64.8, Cu2+=52.9, Co2+=49.2).
