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，新的工藝過程簡單，消耗時間短，不需要浪費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，與鈀銅粉共同進行鈀二次回收，獲得較高的回收率。</p><p

仿真首飾市面上流通的還有少量下列飾品：①包金：就是把黃金打制成極薄的金箔，包在以銅、銀、鋅、鎳等為基體的材料上，加工成各種飾品，這樣既便宜，又給人以黃金相同的感覺。飾品上往往打24KF、18KF印記。②鍍金：是利用電解原理，在金屬基體表面上鍍上一層金膜，一般厚度為10微米以上，金屬基體多為銅、銀、鋅、鎳或它的合金。其特點是金層極薄，鍍制方便，成本很低，有一定的裝飾效果，但金層易被磨損掉，飾品只有短時期的輝煌。首飾上常有18KGP，24KGP印記。③亞金：以銅為基體的仿金材料，表面上往往鍍金。④稀金：實際上不含金，是前幾年出現(xiàn)的一種黃色合金，主要是由銅、鎳等組成的合金，含有少量稀土元素。⑤鈦金：市場上少有出現(xiàn)，也是一種仿金首飾，在基體表面上鍍鈦，生成一種叫TiN的物質(zhì)。另外市場上還出現(xiàn)過被稱作為中國臺灣金、泰國金、鍛壓金的首飾。這些均屬仿金首飾，并不是那些地方產(chǎn)的足金飾品，而是鍍金、包金之類的東西。甚至某些旅游區(qū)市場上還有稱“寶石金”的首飾，這實際上也是鍍金、包金制品。

1、吸收光譜，按實驗方法，分別在相同條件下，于400-650nm波長內(nèi)測定吐溫80-鈀(II)-PAR固相溶解液及相應(yīng)試劑吸光度(見圖1)。在吐溫80固相溶解液中，試劑比較大吸收波長為412nm，鈀(II)-PAR配合物比較大吸收波長為528nm，且不隨時間而變化，故本實驗在528nm處測定。2、鹽的選擇及用量的影響，實驗條件下，分別向吐溫80-PAR水溶液加入氯化銨，硝酸銨，酸銨，氯化鈉，硝酸鈉，檸檬酸三鈉，碳酸鈉，磷酸氫二鈉；結(jié)果表明:氯化鈉，氯化銨不能使體系分相，碳酸鈉分相不完全，硝酸銨，硝酸鈉，磷酸氫二鈉，檸檬酸三鈉，酸銨均能使體系分相；完全分相的鹽量依次分別為12.00，8.00，4.00，1.5克。酸銨使體系分相的效果比較好：用量少，界面清晰，下層水相澄清透明；故選用酸銨作分相鹽。
