style="text-indent:25px">貴金屬回收的意義：1、貴金屬資源稀缺，特別是金、銀工業(yè)儲量較少。2、為了更好的為社會發(fā)展金屬鈀屬于稀有貴金屬，在自然界中的儲藏量很少。鈀碳催化劑回收是非常重要的化工原料，我們國家對鈀的儲藏量及開采量有一定限度。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，達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。鈀碳具有加氫還原性高、選擇性好、性能穩(wěn)定。</p><div

style="text-indent:25px">鈀合金可制成膜片(稱鈀膜)。鈀膜的厚度通常為0.1mm左右。主要于氫氣與雜質(zhì)的分離。鈀膜純化氫的原理是，在300—500℃下，把待純化的氫通入鈀膜的一側(cè)時，氫被吸附在鈀膜壁上，由于鈀的4d電子層缺少兩個電子，它能與氫生成不穩(wěn)定的化學鍵(鈀與氫的這種反應(yīng)是可逆的)，在鈀的作用下，氫被電離為質(zhì)子其半徑為1.5×1015m，而鈀的晶格常數(shù)為3.88×10-10m(20℃時)，故可通過鈀膜，在鈀的作用下質(zhì)子又與電子結(jié)合并重新形成氫分子，從鈀膜的另一側(cè)逸出。在鈀膜表面，未被離解的氣體是不能透過的，故可利用鈀膜獲得高純氫。雖然鈀對氫有獨特的透過性能，但純鈀的機械性能差，高溫時易氧化，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，可改善鈀的機械性能。蘇州德誠擁有鈀的冶煉技術(shù)與先進的生產(chǎn)設(shè)備和豐富的回收經(jīng)驗。江西口碑好硝酸鈀回收電話</p><p
