Contrastive Experimental of the Ultrasonic-Assisted Extraction and Oscillation Extraction of Lead from Soil Using EDTA

Abstract:

Ultrasonic-assisted extraction of lead from red soil using EDTA was investigated, the experimental result was compared with that of oscillation extraction to evaluate the performance of ultrasonic-assisted extraction. The optimum extraction conditions were 0.006 mol/L of EDTA, 0.006 mol/L of EDTA and 90 min of ultrasonic-assisted extraction or 240 min of oscillation extraction. Under the optimum extraction conditions, the extraction rate of 76.33% and 74.30% was obtained for ultrasonic-assisted extraction and oscillation extraction, respectively. The ultrasonic-assisted extraction could shorter the extraction time with a improved extraction rate effectively.
