|zeo-karb;[樹脂]陽離子交換樹脂
陽離子交換樹脂（Cation Exchange Resin）是一種具有離子交換功能的高分子材料，廣泛應用于水處理、化工生産及實驗室分離純化等領域。其核心功能是通過化學作用選擇性吸附溶液中的陽離子，并釋放等量其他陽離子，實現離子置換。
該樹脂由交聯聚合物基質（如聚苯乙烯-二乙烯苯共聚物）構成，表面固定帶有負電荷的功能基團，如磺酸基（-SO₃H）或羧酸基（-COOH）。當接觸含陽離子（如Ca²⁺、Na⁺）的溶液時，樹脂通過以下反應完成交換： $$ R-SO_3^-H^+ + Na^+ rightarrow R-SO_3^-Na^+ + H^+ $$ 其中R代表樹脂骨架，H⁺為可交換離子。
權威研究顯示，磺酸型強酸性陽離子交換樹脂對二價離子的選擇性順序為：Ba²⁺ > Pb²⁺ > Sr²⁺ > Ca²⁺ > Ni²⁺ > Cd²⁺ > Cu²⁺ > Co²⁺ > Zn²⁺ > Mg²⁺（《離子交換與吸附》期刊數據）。
Cation Exchange Resin（陽離子交換樹脂） 是一種高分子材料，主要用于通過離子交換反應吸附溶液中的陽離子（帶正電荷的離子），并釋放自身攜帶的對應離子。以下是詳細解釋：
陽離子交換樹脂表面帶有負電荷基團，通過靜電作用吸附溶液中的陽離子。例如：
