氯化镉制备
2.（光谱纯学）将250ml高纯浓盐酸慢慢加入120g高纯金属镉中，待反应速度缓慢时用电炉微微加热。反应结束后加入100ml电导水进行稀释，过夜，用4*砂芯漏斗滤去过量镉。蒸发浓缩至结晶薄膜形成，冷却结晶，于真空干燥器中进行干燥，得光谱纯氯化镉成品。 3.将氯化镉在低于34℃的温度下，从水溶液中结晶析出，所得产物即为CdCl2·2.5H2O。 4.将等摩尔的硫酸镉溶液和氯酸钡溶液混合。然后过滤并离心分离，得到没有硫酸钡悬浮的澄清溶液。将所得溶液浓缩，析出结晶。因为晶体容易潮解，所以要用五氧化二磷真空干燥2天。 5. 在相对密度为1.19的化学纯盐酸中，一点一点地加入颗粒状工业品 （ 或化学纯）镉： 反应停止后，应有未反应的过量镉存在。加热反应物至40～60℃，分离剩余镉与上层清液，然后在清液中加入少量3%过氧化氢，煮沸5～10min狀 （ 使 Fe 2+离子氧化沉淀） ，略经冷却后，加入稍稍过量的碳酸镉中和游离酸，并加热至80～90℃。静置，滤去过量的碳酸镉和氢氧化铁。滤液用盐酸酸化至ph＝3～4后，蒸发浓缩至出现结晶薄膜、冷却到15～20℃结晶 （ 必要时加入少量氯化镉作为晶种） ，析出的结晶离心甩干，在温度低于33℃条件下干燥，即得成品氯化镉。若得到的成品不是纯白色，则可用水重结晶。
