The drawback of animalcharcoal (easy saturation, polymerization risk etc) on adsorption has really called for a modification of carbon.  In an effort to bridge the gab, Emeraldine supported with MOF-199 Hong Kong University of of Science and Technology MOF (HKUST- 1) metal organic frameworks (POLYMER/Metal Organic Frameworks) composite were used to modify animal charcoal. The effect of Bare Animal Chacoal (BB), Bare Animal Chacoal modified with Emeraldine (BE), Bare Animal Chacoal modified with HKUST-1 metal organic frameworks (BH), Bare Animal Chacoal modified with Emeraldine / HKUST-1 metal organic frameworks (BEH) supported with HKUST- 1 metal organic frameworks composite on adsorption were studied using Ultravioletevisible spectroscopy (UV-vis), scanning electron microscopy (SEM). The UV-vis analyses showed that Emeraldine fiber was in contact with HKUSK-1MOF and both complemented the animal charcoal composite. SEM results revealed that BB and MOFs were well-dispersed and anchored tightly on the polymer composite. The adsorption capacity of the Bare Animal Chacoal and synthesized materials was studied by UV-vis spectroscopy analysis. The pH at which the composite works at optimum is 8, the optimum dosage was found to be 0.3g at a contact time of 100 mins all analysis was carried out at room temperature. Potassium ferrous cyanide as a known probe was used as an adsobate. The langmiur isotherm equation fitted the equilibrium data for Potassium ferrous cyanide sorption.
