采用光束点火技术，研制了一套鲁棒氧瓶燃烧系统。取适量的环境样品，用一小块滤纸包裹，置于铂锆螺旋制成的篮子中。在将样品插入含有酸混合物的充氧烧瓶中后，来自高架投影灯的光束聚焦以点燃样品。通过摇动烧瓶将燃烧产物吸收到酸混合物中，然后用于金属的ICP-AES测量。该方法已成功地应用于环境标准物质和卤虫中金属元素的测定。本方法也适用于以过氧化氢为吸收剂的离子色谱法测定聚氯乙烯墙纸中的氯。
A robust oxygen-flask combustion system was developed using light beam ignition. An appropriate amount of environmental sample was wrapped with a small piece of filter paper and held in a basket made of platinum-zirconium spiral. After the sample was inserted into an oxygen-filled flask containing an acid mixture, the light beam from an overhead projector lamp was focused to ignite the sample. The combusted products were absorbed into the acid mixture by shaking the flask and then used for the ICP-AES measurement of metals. The proposed method was successfully applied to the determination of metals in Environmental Standard Reference Materials and Artemia salina . The present method is also applicable to ion chromatographic measurements of chlorine in polyvinyl chloride wall paper by using hydrogen peroxide as absorbent.
