低鈀合金硝酸溶解生成硝酸鹽溶液后，只有硝酸鈀在弱酸性條件下可水解生成不溶于水的水合氧化鈀，水合氧化鈀在不溶液中溶解度微，是非常適合富集鈀，新生成的水合氧化鈀易溶解于酸，為進(jìn)一步提純分離創(chuàng)造了條件，從而減少試劑消耗和尾液排放，達(dá)到有效提高鈀直收率和回收率。銀銅鈀合金硝酸溶解后，硝酸鹽中只有硝酸鈀在弱酸性溶液中生成水合氧化鈀沉淀，而水合氧化鈀中的溶解度很小很小，從而有效地分離出鈀，且富集量大，**提高了鈀的直收率。工藝中合金用酸溶解后加熱蒸煮，加水趕酸的目的在于極大地減少尾液，使試劑消耗**降低，有效縮短尾液處理時(shí)間。

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)用糖類固體懸浮還原得純銀。銀純度99.9%，直收率98%。此法已申請專利。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)。

從廢定影液中回收銀感光材料經(jīng)過曝光、顯影、定影之后，黑白片上約有70-80%的銀進(jìn)入定影液中，彩**的銀幾乎全部進(jìn)入定影液。從廢定影液中回收銀、在國內(nèi)外均得到高度重視，進(jìn)行了大量的研究工作，采用的回收方法為離子沉淀法、電解法、金屬置換法、yaowu還原法、離子交換法等。電解法的優(yōu)點(diǎn)是提銀后的定影液可返回作定影使用。大陸較大的電影制片廠均使用此法的回收銀。

一、實(shí)驗(yàn)過程分析，1、實(shí)驗(yàn)試劑，在整個(gè)實(shí)過相中,所涉及到的試射均選取為光譜純試制,包括二氧化硅試劑、二氧化鋯試劑、氧化鈣試劑、氧化鎂試劑、酸鍶試劑、以及碳粉試劑。同時(shí),還制備有金、鉑、鈀、鉈的標(biāo)準(zhǔn)溶液：金、鉑、鉈標(biāo)準(zhǔn)溶液的制備方法一致，可簡單概括為——稱取金、鉑、鉈樣品各計(jì)，加入一定量王水，在水浴加熱狀態(tài)下蒸發(fā)，以濃度為6mol/L的鹽酸試劑對其進(jìn)行溶解。溶解后再次加入一定量的水，對其進(jìn)行稀釋（加入水標(biāo)準(zhǔn)為稀釋劑量100毫升）。同時(shí)，鈀標(biāo)準(zhǔn)溶液的制備方法有所不同，可將其概括為——精密稱取劑量為，將其放置于燒杯當(dāng)中，燒杯中同時(shí)注入1毫升劑量的濃鹽酸試劑以及5滴標(biāo)準(zhǔn)濃硝酸試劑。在充分加熱的狀態(tài)下，注入鹽酸。完全溶解后，加入水使其充分稀釋。在此基礎(chǔ)之上，還需要完成對巰基活性炭的制備工作，其具體的制備方法可概括為：在錐形瓶當(dāng)中，加入劑量為20毫升的巰基乙酸成分、以及劑量為14毫升的乙酸酐成分。同時(shí)，向錐形瓶當(dāng)中滴注2滴酸試劑。在對混合試劑充分混合均勻的情況下，向其中注入劑量為20克的活性炭成分，在確保其攪拌均勻的基礎(chǔ)之上，將其放置于恒溫烘箱當(dāng)中進(jìn)行處理（恒溫烘箱控制反應(yīng)溫度為80度，控制反應(yīng)時(shí)間為8小時(shí)）。鈀的沉淀率隨著硝酸濃度的增加而降低。</p><div

style="text-indent:25px">鈀回收主要工藝方法您知道嗎?江蘇專業(yè)硝酸鈀</p><p> 鈀碳性質(zhì)、用途與生產(chǎn)工藝，作用鈀碳是一種催化劑，是把金屬鈀粉負(fù)載到活性碳上制成的，主要作用是對不飽和烴或CO的催化氫化。具有加氫還原性高、選擇性好、性能穩(wěn)定、使用時(shí)投料比小、可反復(fù)套用、易于回收等特點(diǎn)。用于石油化工、醫(yī)藥工業(yè)、電子工業(yè)、香料工業(yè)、染料工業(yè)和其他精細(xì)化工的加氫還原精制過程。分類及用途鈀碳（Pd/C）催化劑是將活性組分鈀通過某種方式負(fù)載于載體活性炭上所制備的一種負(fù)載型催化劑。盡管ChemicalbookPd具有良好的催化性能，但是對于塊狀鈀或海綿鈀來說，其機(jī)械性能差，熱穩(wěn)定性差，且價(jià)格較為昂貴，不適合直接用于催化反應(yīng)。因此人們利用具有一定機(jī)械強(qiáng)度的、較高比表面積的、適宜化學(xué)性質(zhì)的載體對Pd進(jìn)行支撐和分散，使上述問題得到了解決?；钚蕴恳?yàn)槠涓弑缺砻娣e、較好的熱穩(wěn)定性和機(jī)械強(qiáng)度，被用作制備鈀碳（Pd/C）催化劑的載體。Pd/C催化劑具有均相催化劑所不具有的一些優(yōu)勢，因而得到了的研究和應(yīng)用。
