摘要(Abstract)：

通过构建多壁碳纳米管负载氧氯化铋（BiOCl-MWCNT）电化学传感器，以实现同时检测样品中的锌、镉、铅离子，采用原位合成方法制备BiOCl-MWCNT，然后通过滴涂成膜的方式制成电化学传感器；考察缓冲液种类、pH值、富集电位、富集时间等实验条件，优化后结合示差脉冲阳极溶出伏安法（DPASV）同时检测样品中Zn²⁺、Cd²⁺、Pb²⁺。结果表明：BiOCl-MWCNT具有较大的比表面积和卓越的导电性；在pH为4.25醋酸缓冲液、富集电位-1.40 V、富集时间120 s，基于DPASV对Zn²⁺、Cd²⁺、Pb²⁺同时检测，浓度线性范围宽、灵敏度高，并成功应用于矿泉水中Zn²⁺、Cd²⁺、Pb²⁺重金属的检测。因此，该方法可以为食品中Zn²⁺、Cd²⁺、Pb²⁺重金属的检测提供新的技术路线。
