硫(liu)(liu)酸(suan)(suan)銅(tong)，又名藍(lan)礬、石膽，無(wu)機化合物，為透(tou)明的(de)(de)深藍(lan)色(se)結晶或粉(fen)末(mo)，溶(rong)于(yu)水(shui)，水(shui)溶(rong)液呈弱(ruo)酸(suan)(suan)性，顯藍(lan)色(se)。在工業農業上硫(liu)(liu)酸(suan)(suan)銅(tong)的(de)(de)應(ying)用是非常(chang)廣泛的(de)(de)。作為殺菌(jun)劑使用：硫(liu)(liu)酸(suan)(suan)銅(tong)中(zhong)Cu2-離子(zi)是重金(jin)屬離子(zi)，硫(liu)(liu)酸(suan)(suan)銅(tong)多(duo)少錢一(yi)公斤，重金(jin)屬離子(zi)能(neng)使蛋白質(zhi)失(shi)去(qu)(qu)活，病毒由蛋白質(zhi)組成(cheng)，所(suo)以能(neng)殺細菌(jun)和病毒。硫(liu)(liu)酸(suan)(suan)銅(tong)具有腐蝕(shi)性，可以把(ba)腐爛的(de)(de)組織去(qu)(qu)掉，硫(liu)(liu)酸(suan)(suan)銅(tong)粉(fen)末(mo)，促(cu)進(jin)新的(de)(de)組織生(sheng)成(cheng)，同(tong)時(shi)對菌(jun)等真菌(jun)具有殺滅作用，因此是輔助治腺肌胃的(de)(de)有效物質(zhi)。

硫(liu)(liu)(liu)酸(suan)銅(tong)(tong)的(de)(de)作用(yong)機制主要是銅(tong)(tong)離(li)子能(neng)與蛋白質中(zhong)的(de)(de)巰基(ji)結(jie)合，干(gan)擾巰基(ji)酶的(de)(de)活性而達(da)到對病(bing)原(yuan)生物的(de)(de)致死作用(yong)。但在(zai)蝦病(bing)暴發期間，如果多次使(shi)用(yong)硫(liu)(liu)(liu)酸(suan)銅(tong)(tong)消毒，使(shi)池內(nei)藻類(lei)(lei)全部，水清見底，反而會促使(shi)對蝦迅速發病(bing)，因而切(qie)不(bu)可亂(luan)用(yong)，必(bi)須慎重(zhong)為好。硫(liu)(liu)(liu)酸(suan)銅(tong)(tong)水溶(rong)(rong)液對金屬有腐蝕(shi)作用(yong)，不(bu)能(neng)用(yong)金屬容器盛裝溶(rong)(rong)解(jie)。溶(rong)(rong)解(jie)硫(liu)(liu)(liu)酸(suan)銅(tong)(tong)時(shi)水溫(wen)不(bu)能(neng)超過60度，否則(ze)易失(shi)效(xiao)。硫(liu)(liu)(liu)酸(suan)銅(tong)(tong)過量會引起魚類(lei)(lei)組(zu)織壞(huai)死、造血組(zu)織破壞(huai)、肝脂肪增加，同時(shi)還可能(neng)殘(can)留在(zai)魚類(lei)(lei)的(de)(de)鰓、肌(ji)肉和肝內(nei)，妨礙腸道(dao)的(de)(de)吸(xi)收，從(cong)而影響魚類(lei)(lei)的(de)(de)攝食和生長，故不(bu)能(neng)經常使(shi)用(yong)。

硫酸銅(tong)(tong)(tong)(tong)為什么有毒(du)性(xing)，這個(ge)得(de)從它的(de)化(hua)(hua)(hua)學成(cheng)分來說起，大(da)家(jia)都知道硫酸銅(tong)(tong)(tong)(tong)屬于(yu)(yu)重(zhong)鹽，富含(han)銅(tong)(tong)(tong)(tong)離子(zi)，徐州硫酸銅(tong)(tong)(tong)(tong)，能引起人體(ti)蛋白(bai)質(zhi)成(cheng)分變質(zhi)，工業級硫酸銅(tong)(tong)(tong)(tong)，從而人們的(de)身(shen)體(ti)健(jian)康，低濃度的(de)溶液如果不小(xiao)心沾(zhan)到，可立(li)即用(yong)(yong)(yong)(yong)清水沖(chong)洗。高濃度就要(yao)緊(jin)急送醫院。硫酸銅(tong)(tong)(tong)(tong)是制(zhi)(zhi)備其他含(han)銅(tong)(tong)(tong)(tong)化(hua)(hua)(hua)合物的(de)重(zhong)要(yao)原料(liao)，同石灰乳混合可得(de)波爾多液，用(yong)(yong)(yong)(yong)作(zuo)植(zhi)物的(de)殺菌劑(ji)，也用(yong)(yong)(yong)(yong)于(yu)(yu)電解(jie)精(jing)煉銅(tong)(tong)(tong)(tong)時的(de)電解(jie)液。硫酸銅(tong)(tong)(tong)(tong)主要(yao)用(yong)(yong)(yong)(yong)途(tu)：用(yong)(yong)(yong)(yong)于(yu)(yu)制(zhi)(zhi)造其他飼鹽如氯化(hua)(hua)(hua)亞銅(tong)(tong)(tong)(tong)、氯化(hua)(hua)(hua)銅(tong)(tong)(tong)(tong)、焦磷酸銅(tong)(tong)(tong)(tong)、氧化(hua)(hua)(hua)亞銅(tong)(tong)(tong)(tong)、醋(cu)酸銅(tong)(tong)(tong)(tong)、碳酸銅(tong)(tong)(tong)(tong)等。染料(liao)和顏料(liao)工業用(yong)(yong)(yong)(yong)于(yu)(yu)制(zhi)(zhi)造含(han)銅(tong)(tong)(tong)(tong)單(dan)偶氮染料(liao)如活(huo)性(xing)艷藍、活(huo)性(xing)紫等。
