The use of chemically modified cellulose for adsorption of copper ions

The current research was carry out to produce a cost effective biosorbent and to study the biosorption process involved in the adsorption of heavy metal such as copper using treated cellulose. Commercial cellulose and extracted cellulose from pineapple leaf were undergoing alkaline treatment with 5% NaOH. The operational parameters such as temperature, contact time, mass of the adsorbent, and agitation speed were fixed. The samples were then prepared in different pH solutions which were pH 6.2, 7.4, 9.2 and 11.5. In this case, Atomic Absorption Spectrophotometer (AAS) was used to analyse the adsorption efficiency of the adsorbent. The results of the adsorption showed that the commercial cellulose has a great efficiency in removal of copper ion compared to extracted cellulose. The removal of copper ions for commercial cellulose is higher as the pH increase. The result differ for the extracted cellulose due to the some error while doing the research. The characteristic commercial cellulose and extracted cellulose were carried out by using FTIR, TGA and XRD.
