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，熔點1773℃，均高于黃金，但產(chǎn)量*為黃金的1/20，是一種化學穩(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。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WhiteGold，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。為了防止誤導消費者，標準規(guī)定不得使用“K白金”或“白K金”這個名稱，而只能標識為“白色18K黃金”或“白色18K金”，或直接標識為“18K金”。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化鈀，再加鹽酸將鈀沉淀，反復3次后還原得純鈀粉。其工藝中氨水轉化體積很大，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，新的工藝過程簡單，消耗時間短。

廢膠片中回收銀昆明貴金屬研究所使用稀liusuan液洗脫彩片上含銀乳劑層，氯鹽加熱沉淀鹵化銀，氯化培燒或有機溶劑洗滌除有機物，堿性介質用糖類固體懸浮還原得純銀。銀純度99.9%，直收率98%。此法已申請**。物資再生利用研究所（原內貿部物資再生利用研究所）采用硫代liusuan鈉溶液溶解廢膠片上的鹵化銀，溶解過程中加入yizhi劑阻止膠片上明膠的溶解，溶解液經(jīng)電解回收銀，片基回收利用。銀浸出率>99%，回收率98%，銀純度99.9%，此法已應用于工業(yè)生產(chǎn)。 [4] 從廢定影液中回收銀感光材料經(jīng)過曝光、顯影、定影之后，黑白片上約有70-80%的銀進入定影液中，彩**的銀幾乎全部進入定影液。從廢定影液中回收銀、在國內外均得到高度重視，進行了大量的研究工作，采用的回收方法為離子沉淀法、電解法、金屬置換法、yaowu還原法、離子交換法等。電解法的優(yōu)點是提銀后的定影液可返回作定影使用。大陸較大的電影制片廠均使用此法的回收銀。 </p>

style="text-indent:25px">當今社會里，估計每個愛美的人，特別是女人或多或少都有幾款首飾，那么在哪些場合該佩戴哪種首飾值得去斟酌。工作場合戴首飾以簡單為美，如一條精致的項鏈和吊墜的完美搭配，或是一枚造型簡潔的戒指，都會使形象樸實大方；小型聚會時則可以講究點品位，可佩戴耀眼一點的首飾，如大的胸針，鑲有名貴珠寶的鉑金首飾等，這些裝扮在燈光的照射下會把你襯托得更加嫵媚動人；洽談生意時以莊重為先，因為這是一個比較正式的場合，莊重的儀表可以讓你更被信任，這時你只要在正裝上配一條項鏈或一枚胸針也就足矣；情人約會講究協(xié)調自然，這時**重要的就是要注意兩個人之間的首飾佩戴應步調一致、和諧自然。若女人珠光寶氣，而男人“兩袖清風”，則兩人在一起就很不協(xié)調，有一種距離的感覺。比較好兩人戴上情侶首飾，這樣風格統(tǒng)一，讓人一見便知。福建口碑好硝酸鈀公司</p><p
