In order appear the characteristics of hydrotalcite-like compounds as a water treatment agent, the removal ability and mechanism of nitrate, boron, Fluoride was examined.Hydrotalcite-like compounds were formerly considered as one of anion exchanger. However, some part of the anions appeared to be removed by adsorption on the surface hydroxide made by the decomposition of the hydrotalcite-like compounds in water.This new finding can explain the strong removal ability of Boron and Fluoride by hydrotalcite-like compounds. By the application of hydrotalcite-like compound for boron or Fluoride removal in some effluents from steel industry, it is appeared that these compounds are interesting from practical viewpoint

为了揭示类水滑石作为水处理剂的特点，考察了类水滑石对水中硝酸盐、硼、氟的去除能力和机理。然而，部分阴离子似乎被水中类水滑石化合物分解生成的表面氢氧化物吸附而被去除，这一新发现解释了类水滑石化合物对硼和氟的强烈去除能力。通过水滑石类化合物在钢铁工业废水除硼、除氟中的应用，从实用的角度来看，这些化合物是很有价值的。
