style="text-indent:25px">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。</p><div

1）浸出法是用酸（**酸鈉、鹽酸-雙氧水或王水）將鈀從廢催化劑中浸出，過濾后，用鐵粉或鋅粉置換濾液中的鈀。得到的粗鈀再次用混酸或王水溶解后，采用氯鈀酸銨沉淀法和二氯二胺絡(luò)亞鈀法提純，得到高純度的海綿鈀。該法的鈀浸出率低、浸出時間較長，但廢催化劑中的鈀不易流失。 2）焚燒法是將廢催化劑高溫下焙燒，除去其中的碳和有機物，以堿性甲醛溶液或甲酸還原燒渣，過濾后，用鹽酸-雙氧水或王水將濾渣溶解，得到鈀溶液。鈀溶液通過離子交換樹脂得到氯化亞鈀或采用氨水絡(luò)合和酸化沉鈀，***用水合肼還原得到純海綿鈀。用此法應(yīng)設(shè)法減少在焚燒過程中鈀的流失 </p><div style="width:100%;text-align:
