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(chǔ)量較少。2、為了更好的為社會(huì)發(fā)展金屬鈀屬于稀有貴金屬，在自然界中的儲(chǔ)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(duì)鈀的儲(chǔ)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(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，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。鈀碳回收廢鈀碳的貯存措施有哪些呢？湖北口碑好硝酸鈀詢問報(bào)價(jià)</p><p

稀金稀金并不是一種單獨(dú)的金屬，而是一些稀有金屬的合金。由于稀金具有某些可與黃金相媲美的特性，如象黃金一樣的色澤，同黃金一樣的化學(xué)穩(wěn)定性和相似的機(jī)械性能。用稀金制做的首飾幾乎可達(dá)到與金首飾亂真的程度。金銀鉑鈀依據(jù)GB11887－2002《首飾貴金屬純度的規(guī)定及命名方法》，市場(chǎng)上銷售的貴金屬首飾可分為金首飾、銀首飾、鉑首飾和鈀首飾4種。鈀首飾鈀鈀這個(gè)貴金屬是2006年才單獨(dú)被制作為首飾的，以往都是在鉑首飾中作為摻合物，是貴金屬首飾家族中又一個(gè)新成員。市面上流行的鈀首飾主要有Pd950和Pd990。①Pd950，要求鈀的含量不得低于950‰，可標(biāo)識(shí)為Pd950或鈀950。②Pd990，要求鈀的含量不得低于990‰，可標(biāo)識(shí)為Pd990或鈀990。含鈀量不低于750‰ 和500‰的鈀首飾主要用于鑲嵌。不允許將鈀首飾稱作為“鈀白金首飾”、“鈀鉑金首飾”等含混名稱。另外，標(biāo)準(zhǔn)規(guī)定還要求，貴金屬首飾的重量要保留兩位小數(shù)，單件重量在100克以內(nèi)的飾品，其重量負(fù)偏差不得大于0．01克。 </p> <p> <br /> </p> <p> <br /> 江西專業(yè)硝酸鈀公司</p><p
