鉑金白金是鉑（Pt）的別稱或俗稱，是一種比白金首飾黃金價值更高的貴金屬。密度21.43g/cm3，熔點(diǎn)1773℃，均高于黃金，但產(chǎn)量*為黃金的1/20，是一種化學(xué)穩(wěn)定性更好，比黃金更稀少、更名貴、更具有保值增值性的貴金屬。近幾年鉑首飾十分流行，特別是鉑鑲嵌首飾更是受人們喜愛。 </p> <p> <br /> </p> <p> 金“K白金”并不是K鉑金，而是一種白色的K黃金（英文名稱為White Gold，即白色金），而白金（鉑）英文名稱為Platinum。市面上銷售的所謂18K白金首飾實(shí)際上是白色的18K黃金飾品，它保證其中黃金含量不低于750‰，其余的是銅、鋅、鎳、銀、鈀、銠等。因成分比例不同，還可產(chǎn)生不同的顏色，即18K彩色金首飾。為了防止誤導(dǎo)消費(fèi)者，標(biāo)準(zhǔn)規(guī)定不得使用“K白金”或“白K金”這個名稱，而只能標(biāo)識為“白色18K黃金”或“白色18K金”，或直接標(biāo)識為“18K金”。

style="text-indent:25px">傳統(tǒng)的低鈀合金回收方法是先將廢料用硝酸溶解后經(jīng)趕硝趕酸后加氨水轉(zhuǎn)化鈀，再加鹽酸將鈀沉淀，反復(fù)3次后還原得純鈀粉。其工藝中氨水轉(zhuǎn)化體積很大，過濾困難，加鹽酸酸沉銀后溶液中鈀鹽溶解量較大，特別是對低鈀合金或含銅、鋅等廢料，鈀碳回收率很低，約為80%。而這種新的回收工藝方法較傳統(tǒng)工藝所沒有的優(yōu)點(diǎn)，新的工藝過程簡單，消耗時間短，不需要浪費(fèi)大量溶液的趕硝過程，將鈀轉(zhuǎn)化為水合氧化鈀有效富集后，使得試劑消耗降低，省略了氯化銀洗滌過程，提高鈀直收率；避免了銅、鎳等賤金屬對氨水的消耗量，節(jié)約氨水80%，降低了成本；這種新工藝中將鈀鹽洗液調(diào)pH值后還原得粗鈀粉，與鈀銅粉共同進(jìn)行鈀二次回收，獲得較高的回收率。廢海綿鈀的回收價值到底如何呢？</p><div

鈀是化學(xué)性質(zhì)**生動的貴金屬，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)。火法工藝常用于鈀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?；鸱üに嚨玫降拟Z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。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。海綿鈀是什么您知道嗎？浙江海綿鈀高價回收</p><p
