鉑金即白金。是一種非常珍貴的貴金屬，與金、銀相比，它用于首飾制造的時(shí)間較晚。由于鉑具有艷麗的白色，優(yōu)異的延展性以及耐磨、耐酸性，從19世紀(jì)開(kāi)始，它就開(kāi)始廣泛應(yīng)用于首飾制造中。鉑類(lèi)金屬在地殼中的自然儲(chǔ)量為8萬(wàn)噸，可開(kāi)采儲(chǔ)量7.1萬(wàn)噸，其中，鉑占50%，鈀占35%，釕占9%，銠占6%。2004年，世界鉑類(lèi)金屬開(kāi)采量為467噸，世界鉑的開(kāi)采量為214噸，其中南非開(kāi)采鉑160噸，俄羅斯36噸，加拿大7噸，美國(guó)4噸;2004年，世界銠的開(kāi)采量為188噸，其中南非開(kāi)采78.5噸，俄羅斯74噸，美國(guó)13.7噸，加拿大12噸。

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。 </p> <p> <br /> </p> <p> <br /> </p><p style="text-indent:25px">目前，鈀碳回收主要用于生產(chǎn)氧化鈀，然后利用氧化鈀制備一系列相應(yīng)的催化劑。從廢鈀催化劑中回收鈀的關(guān)鍵在于鈀的浸出，隨著浸出方法的不同，派生出不同的工藝。目前，普遍采用的是用硝酸或王水浸出，氨絡(luò)合沉淀的工藝。由于鈀催化劑中除了活性鈀以外還有輔助催化劑如銅、鋁等元素，另外還有載體，如碳、硅等。對(duì)于特種催化劑，鈀的回收也有所不同，目的是把金屬鈀提煉出來(lái)，達(dá)到高純度和高回收率。文中所用的廢鈀催化劑是以二氧化硅為載體的鈀催化劑，其中還含有銅和鋁等成分。鈀碳是一種黑色粉末狀顆粒的化學(xué)物質(zhì)。</p><div

style="text-indent:25px">鈀碳回收廢鈀碳的貯存措施有哪些呢？山西專(zhuān)業(yè)硝酸鈀</p><p style="text-indent:25px">鈀管純化氫的原理是，在300—500℃下，把待純化的氫通入鈀管的一側(cè)時(shí)，氫被化學(xué)吸附在鈀管壁上并解離成氫原子，氫原子與鈀原子形成合金型氫化物，氫原子占據(jù)金屬晶格中的空隙位置，也稱(chēng)間充型氫化物。在濃度梯度的作用下，氫原子可在鈀管壁中擴(kuò)散，通過(guò)鈀管后重新形成氫分子脫附析出，故可利用鈀管獲得高純氫。雖然鈀對(duì)氫有獨(dú)特的透過(guò)性能，但純鈀的機(jī)械性能差，高溫時(shí)易氧化，再結(jié)晶溫度低，易使鈀管變形和脆化，故不能用純鈀作透過(guò)膜。在鈀中添加適量的IB族和Ⅷ族元素，制成鈀合金，可改善鈀的機(jī)械性能。應(yīng)用的鈀合金中，銀約占20—30%，其他成分（如金等）的含量<5%。氫透過(guò)鈀合金的速率與溫度、膜的厚度及滲透摸兩側(cè)的原料氫和純氫的壓力差（△P）有關(guān)。升高溫度，增大△P及減小膜的厚度，會(huì)使透氫速率增加。但溫度升高，將使?jié)B透膜的抗拉強(qiáng)度降低。因此，鈀管的使用溫度通?？刂圃?50℃以下。某些雜質(zhì)可導(dǎo)致鈀中毒，使透氣性能變壞，甚至可使膜遭到破壞。能引起鈀中毒的物質(zhì)有：汞、砷化物、鹵化物、油蒸氣、含硫和含氨物質(zhì)以及粉塵等。山西專(zhuān)業(yè)硝酸鈀</p><p
