珠江口海域是河水与海水交汇区域,环境非常复杂,要进行重金属的河口化学研究,首先必须了解其在河口区的化学形态及变化规律,才能在实验室进行模拟实验和理论计算。这对河口海域的环境保护是具有重要意义的。 目前,对海水中微量金属的化学形态研究颇为活跃,大体可分二大类。其研究方法见表1。 The Pearl River estuary area is a confluence of river water and seawater. The environment is very complicated. To study the chemical chemistry of estuaries in heavy metals, we must first understand the chemical forms and changes in the estuarine area before conducting simulation experiments and theoretical calculations in the laboratory. This is of great significance to the environmental protection of estuaries. At present, the study on the chemical forms of trace metals in seawater is quite active, which can be divided into two broad categories. The research methods in Table 1.
