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 />

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)開始，它就開始廣泛應(yīng)用于首飾制造中。鉑類金屬在地殼中的自然儲(chǔ)量為8萬(wàn)噸，可開采儲(chǔ)量7.1萬(wàn)噸，其中，鉑占50%，鈀占35%，釕占9%，銠占6%。2004年，世界鉑類金屬開采量為467噸，世界鉑的開采量為214噸，其中南非開采鉑160噸，俄羅斯36噸，加拿大7噸，美國(guó)4噸;2004年，世界銠的開采量為188噸，其中南非開采78.5噸，俄羅斯74噸，美國(guó)13.7噸，加拿大12噸。

黃金、白銀飾品在人類幾千年的歷史中始終是財(cái)富和華貴的象征。隨著社會(huì)的發(fā)展和高科技的出現(xiàn)，用金銀制作的珠寶、飾品、擺件的范圍和樣式不斷拓寬深化?，F(xiàn)如今，隨著人們收入的不斷提高、財(cái)富的不斷增加，黃金、白銀飾品的需求量也在逐年增加。工業(yè)與高新技術(shù)產(chǎn)業(yè)由于黃金、白銀等貴金屬所持有的物理、化學(xué)性質(zhì)，良好的導(dǎo)電性、導(dǎo)熱性、工藝性，極易加工成超薄金箔、微米金絲和金粉，很容易鍍到其他金屬、陶器及玻璃的表面上；極高抗腐蝕的穩(wěn)定性，在一定壓力下金容易被熔焊和鍛焊；可制成超導(dǎo)體與有機(jī)金等，使它廣泛應(yīng)用于工業(yè)和現(xiàn)代高新技術(shù)產(chǎn)業(yè)中，如電子、通信、宇航、化工、醫(yī)療等領(lǐng)域。

鈀是化學(xué)性質(zhì)**生動(dòng)的貴金屬，運(yùn)用此性質(zhì)在濕法工藝收回鈀的進(jìn)程中，能夠較為方便地使鈀與賤金屬和其他貴金屬分隔。濕法工藝收回鈀的基本思路是運(yùn)用鈀能夠溶解于硝酸的特性使鈀與金和鉑等難溶于硝酸的貴金屬分隔，然后運(yùn)用銀能夠在鹽酸或氯化鈉溶液中生成氯化銀沉積的性質(zhì)，使銀從含鈀硝酸溶液中別離（簡(jiǎn)稱為分銀）。在分銀后的溶液中參加能夠使鈀離子沉積的試劑，到達(dá)與其他賤金屬別離的目的。濕法工藝能夠得到含量到達(dá)?；鸱üに嚦Ｓ糜阝Z含量較低的廢猜中收回鈀，或者在收回其他貴金屬的火法工藝中富集鈀。火法工藝得到的鈀一般為粗鈀，一般還必須用濕法工藝進(jìn)行精制提純得到高純度海綿鈀或直接加工成鈀的精密化學(xué)品。(1)含鈀廢液中鈀的收回在濕法工藝收回廢家電中的金和銀的造液進(jìn)程中，鈀很容易與金和銀一同進(jìn)入溶液。含鈀廢液中鈀的存在形狀主要為Pd(Ⅳ)和Pd(Ⅱ)氧化態(tài)的鈀'其傳統(tǒng)的別離和富集辦法是氯鈀酸銨沉積法和二氯二氨絡(luò)亞鈀法。鈀碳回收后對(duì)廢鈀催化劑中的貴金屬鈀進(jìn)行提取具有非常高的經(jīng)濟(jì)價(jià)值。河南口碑好硝酸鈀高價(jià)回收</p><p

鉑族元素具有許多優(yōu)良的性能，被很多地應(yīng)用于石油、化工、電子、儀器儀表，隨著科學(xué)技術(shù)的發(fā)展，其應(yīng)用范圍越來(lái)越很多。鉑族元素在地殼的含量極少，鈀在地殼中含量稀少，產(chǎn)量有限，價(jià)格昂貴。因而各種準(zhǔn)確的測(cè)定方法都建立在適當(dāng)?shù)姆蛛x富集方法之上，常采用火試金、溶劑萃取、離子交換和吸附分離法。聚酰胺是1928年由杜邦公司研制的很多用于機(jī)械業(yè)的一種塑料纖維，又名尼龍或錦綸，價(jià)格低廉，已成功地用于金、銀、鉻、汞等元素的富集分離，但用于鈀的分離富集報(bào)道較少。在鹽酸或王水介質(zhì)中，它對(duì)鈀(II)有很強(qiáng)的吸附能力，且該樹脂可改性成泡塑狀纖維，改性后的樹脂在合適條件下對(duì)鈀的吸附性能更好，使用也更為方便。這邊分析聚酰胺、改性聚酰胺樹脂對(duì)微量鈀的比較好吸附分離和解脫條件，結(jié)合原子吸收光度法測(cè)定，建立了一個(gè)可用于礦石中微量鈀的富集分離和測(cè)定的方法，應(yīng)用于實(shí)際樣品分析結(jié)果符合要求。
