生产制备方法及用途展开↓

制备方法

1.电解法以金属铜为原料,溶解于浓硫酸。配成电解液组成为:含Cu52.3 g/L、H2SO4约200 g/L,电解液温度58.5℃,槽电压0.33 V,阴极电流密度1.82 A/cm2。经电解精炼,制得高纯铜粉成品。 2.将硝酸铜进行重结晶、干燥,并在800～850℃下灼烧以除去氮的氧化物。然后,把制得的氧化铜放入管式炉内的瓷皿中,并在250～300℃的条件下用氢气进行还原。用此法制得的铜呈粉红色粉末状,在较高温度(800～900℃)时,铜可黏结起来,而得到海绵状物质。 3.向硫酸铜的浓溶液中放入过量的锌棒、锌块或锌粉,通过置换反应使铜析出。当溶液褪色后,回收未起反应的锌,同时用加热到60～70℃的稀硫酸或稀盐酸浸泡含锌残渣的沉淀铜。在锌被完全溶解后,将沉淀铜转移至过滤器上,然后用稀盐酸、水洗涤,最后用乙醇洗涤,并在40～50℃的条件下将铜烘干。这一制法中也可用铁或铝来替代锌。 4.粉末状氧化铜,在管式炉中于135～150℃下通氢气还原,直至黑色氧化铜转变为玫瑰色铜粉为止。 停止加热,继续通氢气冷却,即可制得成品。若要制取在空气中相当稳定的粘结体,还原温度要控制在500～520℃ 5.先将工业铜用稀硝酸 ( 或稀硫酸)和蒸馏水洗去表面污物,然后用硝酸 ( 或硫酸)溶解,作为电解液,采用较纯铜片作为阴极,电流密度控制在120A/m2,电解产物根据产品要求,可以经水洗、酸洗、脱水、干燥。

合成制备方法

1.电解法以金属铜为原料，溶解于浓硫酸。配成电解液组成为：含Cu52.3 g/L、H2SO4约200 g/L，电解液温度58.5℃，槽电压0.33 V，阴极电流密度1.82 A/cm2。经电解精炼，制得高纯铜粉成品。

2.将硝酸铜进行重结晶、干燥，并在800～850℃下灼烧以除去氮的氧化物。然后，把制得的氧化铜放入管式炉内的瓷皿中，并在250～300℃的条件下用氢气进行还原。用此法制得的铜呈粉红色粉末状，在较高温度(800～900℃)时，铜可黏结起来，而得到海绵状物质。

3.向硫酸铜的浓溶液中放入过量的锌棒、锌块或锌粉，通过置换反应使铜析出。当溶液褪色后，回收未起反应的锌，同时用加热到60～70℃的稀硫酸或稀盐酸浸泡含锌残渣的沉淀铜。在锌被完全溶解后，将沉淀铜转移至过滤器上，然后用稀盐酸、水洗涤，最后用乙醇洗涤，并在40～50℃的条件下将铜烘干。这一制法中也可用铁或铝来替代锌。

4.粉末状氧化铜，在管式炉中于135～150℃下通氢气还原，直至黑色氧化铜转变为玫瑰色铜粉为止。
停止加热，继续通氢气冷却，即可制得成品。若要制取在空气中相当稳定的粘结体，还原温度要控制在500～520℃

5.先将工业铜用稀硝酸 （ 或稀硫酸）和蒸馏水洗去表面污物，然后用硝酸 （ 或硫酸）溶解，作为电解液，采用较纯铜片作为阴极，电流密度控制在120A/m2，电解产物根据产品要求，可以经水洗、酸洗、脱水、干燥。

2.对环境的影响:

一、健康危害

侵入途径：吸入、食入。  健康危害：动物吸入铜的粉尘和烟雾，可引起呼吸道刺激症状，发生支气管炎或支气管肺炎，甚至肺水肿。长期接触铜尘的工人常发生接触性皮炎和鼻眼的刺激症状，引起烟痛、鼻塞、鼻炎、咳嗽等症状。铜熔炼工人可发生铜铸造热。长期吸入尚可引起肺部纤维组织增生。铜的毒性较小，但铜过剩出可引起中毒。铜盐的毒性以CuAc2和CuSO4较大，经口服即使微量也会引起急性中毒，发生流涎、恶心、呕吐、阵发性腹痛，严重者可有头痛、心跳迟缓、呼吸困难甚至虚脱，也可引起中枢神经系统的损害。

二、毒理学资料及环境行为

急性毒性： 属微毒类。铜的污染来源为冶金、电镀、催化、仪表、合金和化工等的废水和废渣。自然界的铜化合物以一价或二价状态存在。一价铜多存在于矿物中，有氧化亚铜形式和硫化亚铜形式。环境中的铜主要以二价铜离子存在，二价铜可和无机配位体NH3、CO32-、HCO3-、SO42-形成络合物。

迁移转化：利用含铜废水灌溉农田或施用含铜污泥，铜可积蓄在土壤中。随水进入到土壤中的铜可被土壤吸持。土壤中的腐殖酸、富里酸含 有羧基、酚基、羰基等含氧基团，能与铜形成螯合物而固定铜。

危险特性：其粉体遇高温、明火能燃烧。  燃烧(分解)产物：氧化铜。

中国(GB5058.3-1996) 固体废弃物浸出毒性鉴别标准值 50mg/L
6.应急处理处置方法:

一、泄漏应急处理

隔离泄漏污染区，周围设警告标志，切断火源。应急处理人员戴好防毒面具，穿一般消防防护服。避免扬尘，使用无火花工具收集于干燥净洁有盖的容器中，转移回收。当水体受到污染时，可采用加入纯碱中和，使铜以碱式碳酸铜形式沉淀而从水中转入污泥中，而污泥再做进一步的无害化处理。对于受铜污染的土壤，可采取排土、土层改良、深耕、施加石灰质矿物及磷酸钙等措施治理。

二、防护措施

一般不需特殊防护，但需防止烟尘危害。

三、急救措施

皮肤接触：脱去污染的衣着，用肥皂水及清水彻底冲洗。就医。  眼睛接触：立即翻开上下眼睑，用流动清水或生理盐水冲洗至少15分钟。就医。  吸入：迅速脱离现场至空气新鲜处。就医。  食入：误服者立即漱口，饮牛奶或蛋清。就医。

灭火方法：干粉、砂土。禁止用水。
