結果表明:當進水中重金屬離子( hg2 + )濃度較低時,弱堿性陰離子交換樹脂對飲用水中hg2 +的去除效果要明顯優于陽離子交換樹脂;當原水中含有相對較高濃度的陽離子( ca2 + 、 mg2 + )時,弱堿性陰離子交換樹脂對水中的重金屬離子具有很高的選擇去除性,而陽離子交換樹脂的選擇去除性卻很差;天然原水中能與重金屬離子( hg2 + )發生絡合反應的陰離子(如: cl ) ,可以使陽離子交換樹脂喪失了對水中微量重金屬離子( hg2 + )的去除作用,而對弱堿性陰離子交換樹脂( d301g型)去除水中微量hg2 +的影響卻很小。The results showed obvious damage to the photosynthetic systems, protective enzyme systems and membrane systems by all the selected heavy metal ions
