摘要
研究了用微量进样-微波等离子体炬发射光谱法(MPTAES)测定锌的方法,考察了微波功率、载气流量、酸浓度等实验参数对锌发射强度的影响。方法测定锌的检出限为1.2ng/ml。对实际样品进行的分析令人满意。
The determination of trace zinc by microwave plasma torch-atomic emission spectrometry with micro-sample introduction system was studied. The effect of microwave power, flow rate of carrier gas and concentration of acids on the emission intensity of zinc was examined, The detection limit of zinc line at 213.9 nm was 1.2 ng/ml. The practical samples were analyzed with satisfactory results.
