摘　　要：利用微波消解样品,再以电化学方波溶出伏安法检测样品中铅的含量并确定了最佳测定条件。结果表明,以微波消解-方波溶出电化学方法分析样品中铅含量,方法简便、快速、灵敏、准确。A new electrochemical method was established to analyze lead in samples by voltammetry of square wave leaching after pre-treatment of microwave irradiating digestion, and the optimum determination conditions were explored. The results showed that for determination of lead content, the microwave digestion-voltammetry of square wave leaching was quick, convenient, sensitive and accurate.
