Additionally,the proposed procedure is fast, of high precision and accuracy and can be employed for quantification of lead(II) in natural water samples, where the results obtained showed a lower influence of the matrices on the procedure response. All the results obtained using the optimized experimental and voltammetric parameters confirmed the practicality and viability of the proposed procedure, providing an important tool for quantification of lead ions in natural water samples. The use of SWV is faster and more sensitive than other conventional techniques. Besides, the use of HAP/Pt enables direct analysis
of water samples without preparation or cleaning of the sample
