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，標準規(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克以內的飾品，其重量負偏差不得大于0．01克。 </p> <p> <br /> </p> <p> <br />

1、吸收光譜，按實驗方法，分別在相同條件下，于400-650nm波長內測定吐溫80-鈀(II)-PAR固相溶解液及相應試劑吸光度(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。 </p> <p> <br /> </p><p> 鈀是化學性質**生動的貴金屬，運用此性質在濕法工藝收回鈀的進程中，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，然后運用銀能夠在鹽酸或氯化鈉溶液中生成氯化銀沉積的性質，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，到達與其他賤金屬別離的目的。濕法工藝能夠得到含量到達?；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?；鸱üに嚨玫降拟Z一般為粗鈀，一般還必須用濕法工藝進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程中，鈀很容易與金和銀一同進入溶液。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亞鈀法。鈀碳是什么您知道嗎？</p><div
