style="text-indent:25px">傳統(tǒng)的萃取分離法主要是采用與水互不相溶的有機(jī)溶劑作萃取溶劑，有的反應(yīng)速度慢，傳質(zhì)速率低，分配比較小而需要在振蕩器上進(jìn)行較長(zhǎng)時(shí)間振蕩或多次萃取才能達(dá)到定量萃取的目的。均相萃取、異相分離萃取體系可以克服異相萃取分離技術(shù)中的一些缺點(diǎn)而受到重視。本文以乙醇為萃取溶劑，均相萃取、異相分離Pd(II)。試驗(yàn)表明liusuan銨存在下乙醇與水分相過(guò)程中，鈀(II)與碘負(fù)離子開(kāi)成的二階碘化鈀負(fù)離子與質(zhì)子化乙醇形成電中性的締合物乙醇與二階碘化鈀負(fù)離子被乙醇相萃取，能使鈀(II)從鐵(III)、鋁(III)、鋅(II)、錳(II)、錫(II)、鉻(III)、鈷(II)的混合溶液中分離。該體系萃取分離鈀，與傳統(tǒng)的鹽酸-(β-巰基氫化肉桂酸異戊酯)-苯體系和liusuan-(β-巰基-β-苯丙酰苯)-三氯甲烷體系相比，具有不使用youdu溶劑、試劑用量少、分離成本低、分離迅速、操作簡(jiǎn)便等優(yōu)點(diǎn)。</p><p style="text-indent:25px">傳統(tǒng)的低鈀合金回收方法是先將廢料用硝酸溶解后經(jīng)趕硝趕酸后加氨水轉(zhuǎn)化鈀，再加鹽酸將鈀沉淀，反復(fù)3次后還原得純鈀粉。其工藝中氨水轉(zhuǎn)化體積很大，過(guò)濾困難，加鹽酸酸沉銀后溶液中鈀鹽溶解量較大，特別是對(duì)低鈀合金或含銅、鋅等廢料，鈀碳回收率很低，約為80%。而這種新的回收工藝方法較傳統(tǒng)工藝所沒(méi)有的優(yōu)點(diǎn)，新的工藝過(guò)程簡(jiǎn)單，消耗時(shí)間短，不需要浪費(fèi)大量溶液的趕硝過(guò)程，將鈀轉(zhuǎn)化為水合氧化鈀有效富集后，使得試劑消耗降低，省略了氯化銀洗滌過(guò)程，提高鈀直收率；避免了銅、鎳等賤金屬對(duì)氨水的消耗量，節(jié)約氨水80%，降低了成本；這種新工藝中將鈀鹽洗液調(diào)pH值后還原得粗鈀粉，與鈀銅粉共同進(jìn)行鈀二次回收，獲得較高的回收率。從高放廢液中分離回收鈀，對(duì)節(jié)約原料和解決這種需求問(wèn)題就具有重要意義。</p><div

廢膠片中回收銀昆明貴金屬研究所使用稀liusuan液洗脫彩片上含銀乳劑層，氯鹽加熱沉淀鹵化銀，氯化培燒或有機(jī)溶劑洗滌除有機(jī)物，堿性介質(zhì)用糖類(lèi)固體懸浮還原得純銀。銀純度99.9%，直收率98%。此法已申請(qǐng)專利。物資再生利用研究所（原內(nèi)貿(mào)部物資再生利用研究所）采用硫代liusuan鈉溶液溶解廢膠片上的鹵化銀，溶解過(guò)程中加入yizhi劑阻止膠片上明膠的溶解，溶解液經(jīng)電解回收銀，片基回收利用。銀浸出率>99%，回收率98%，銀純度99.9%，此法已應(yīng)用于工業(yè)生產(chǎn)。
