吴景云等用原子吸收分光光度法测定海洋沉积物中多种元素时,提出氢氟酸-硝酸-高氯酸溶剂和硝酸过氧化氢溶剂的湿法溶解海洋沉积物,认为是较好的分解海洋沉积物的方法。但是,这种湿法分解样品,要加入多种大量化学试剂。因此,难免带来污染和开放性加热挥发、溅洒损失以及金属或玻璃器皿受高热与强酸的腐蚀或吸附引起误差,而且需要经多次加热、蒸煮,操作复杂又费时。湿法也不宜在船上进行现场的样品分解,对海上采集样品的保存和运输中,沾污难以控制。大洋水中悬浮体含量极少,
Wu Jingyun and other atomic absorption spectrophotometric determination of a variety of marine sediment elements proposed hydrofluoric acid - nitric acid - perchloric acid solvent and nitric acid hydrogen peroxide solvent wet dissolving marine sediment that is better decomposition of the ocean Sediment method. However, this wet-disintegration sample requires the addition of a large variety of chemicals. Therefore, it is inevitable to bring pollution and open heat evaporation, spatter loss and metal or glassware by high heat and acid corrosion or adsorption error, but also by repeated heating, cooking, the operation is complex and time-consuming. The wet method is also not suitable for on-site sample decomposition on board, it is difficult to control the contamination of the collected and transported samples at sea. Ocean water content of suspended solids is minimal,
