Determination of Nine Hazardous Elements in Textiles by Inductively Coupled Plasma Optical Emission Spectrometer after Microwave-Assisted Dilute Nitric Acid Extraction
Textiles are easily contaminated by heavy metals in the course of processing. In order to monitor the quality of textiles, a new method was developed for simultaneous determination of arsenic, antimony, lead, cadmium, chromium, cobalt, copper, nickel and mercury in textiles by inductively coupled plasma optical emission spectrometry (ICP-OES) after microwave-assisted dilute nitric acid extraction. After optimizing extraction conditions, we ultimately selected 5% nitric acid as extractant and 5 min as extraction time with the extraction temperature of 120 ℃ and instrument power of 400W in the microwave-assisted extraction procedure. Nine hazardous elements were detected sequentially by ICP-OES. The results showed that the detection limits were 0.3~15 μg·L-1 and the recoveries 73.6%~105% with the RSDs (n=3) of 0.1%~3%. The proposed method was successfully used to determine nine elements in cotton, wool, terylene and acrylic.
