| Abstract | Acid digestion is important in solubilizing metal ions in heavy metals determination. A number of procedures exists and the one used is dependent on different factors. This work is aimed at investigating the performance of three different acid digestion procedures (Aqua Regia, 2 M HNO3and HNO3/HClO4) for the extraction of Pb, Cd and Zn in soil sample from an abandoned dumpsite of a lead-acid producing industry in Lalupon, Oyo State. Heavy metals in soil extracts were determined using atomic absorption spectrophotometer. Results revealed that Aqua Regia gave the highest contents level of Pb and Cd, HNO3/HClO4 showed best performance for Zn while 2 M HNO3 had the least performance for the metals considered. Result of 2 M HNO3 was less than the other two and could not represent total metal content of the soil. Without losing focus of the objectives of research, variation in the effectiveness of acid digestion proceduresshould be borne in mind when making a choice. |
