Abstract

This research is to analyze the poly(hydroxamic acid) resin as one of the polymer that can absorb metal ion especially ferum and cuprum. This research is to study the sorption capacity of metal ion especially iron and copper metal ion. Secondly is to research the rate of exchange capacity of the metal ion especially copper. The analysis is using the batch technique where each of the solution of polymer that contain about 0.2 gram was added with 20ml of vary acidity of buffer solution and water before the adding of vary ppm(part per million) of metal ion standard solution (Cu2 + and Fe3 + standard solution). The analysis of cuprum and ferum in the presence of poly(hydroxamic acid) chelating resin is to search the amount of each metal ion that can be absorb by resin or polymer in each gram of absorbance(polymer). Where the binding of the polymer with the metal ion is depend to the acidity of the solution used. From the analysis it's was found that the cuprum (Cu2+) is absorb by the polymer much better than the ferum (Fe3+. And at the high acidity condition the capacity of metal ion absorbs is much lower than the lower acidity. The highest number of absorb metal ion for ferum was 0.0525mg/g resin at the pH6. For cuprum metal ion the highest amount absorbs by polymer is also at the pH6 with the ppm5 that absorb about 0.1425mg/g resin. Totally the exchange capacity is increasing. And the capacity of metal ion absorb is depending on its solution acidity is increasing with the decreasing of acidity.
