Abstract
Coconut powder was used as modifier for carbon paste electrode for voltammetric determination of lead ions in aqueous samples. Different parameters like electrode composition, different electrolytes, electrolyte concentration, different pH values, deposition time and deposition potential were optimized for application of Coconut powder modified electrodes. The use of 0.2M HCl as supporting electrolyte and 20 % (w/w) modifier, deposition time 390 sec and deposition potential –1800mV gave an optimum current response for lead (II) solution. Results showed that the modified carbon paste electrode can determine Lead with better sensitivity in aqueous solutions.
