稀金稀金并不是一種單獨(dú)的金屬，而是一些稀有金屬的合金。由于稀金具有某些可與黃金相媲美的特性，如象黃金一樣的色澤，同黃金一樣的化學(xué)穩(wěn)定性和相似的機(jī)械性能。用稀金制做的首飾幾乎可達(dá)到與金首飾亂真的程度。金銀鉑鈀依據(jù)GB11887－2002《首飾貴金屬純度的規(guī)定及命名方法》，市場(chǎng)上銷售的貴金屬首飾可分為金首飾、銀首飾、鉑首飾和鈀首飾4種。鈀首飾鈀鈀這個(gè)貴金屬是2006年才單獨(dú)被制作為首飾的，以往都是在鉑首飾中作為摻合物，是貴金屬首飾家族中又一個(gè)新成員。市面上流行的鈀首飾主要有Pd950和Pd990。①Pd950，要求鈀的含量不得低于950‰，可標(biāo)識(shí)為Pd950或鈀950。②Pd990，要求鈀的含量不得低于990‰，可標(biāo)識(shí)為Pd990或鈀990。含鈀量不低于750‰ 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(biāo)準(zhǔn)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(nèi)的飾品，其重量負(fù)偏差不得大于0．01克。 </p> <p> <br /> </p> <p> <br />

style="text-indent:25px">傳統(tǒng)的萃取分離法主要是采用與水互不相溶的有機(jī)溶劑作萃取溶劑，有的反應(yīng)速度慢，傳質(zhì)速率低，分配比較小而需要在振蕩器上進(jìn)行較長(zhǎng)時(shí)間振蕩或多次萃取才能達(dá)到定量萃取的目的。均相萃取、異相分離萃取體系可以克服異相萃取分離技術(shù)中的一些缺點(diǎn)而受到重視。本文以乙醇為萃取溶劑，均相萃取、異相分離Pd(II)。試驗(yàn)表明liusuan銨存在下乙醇與水分相過(guò)程中，鈀(II)與碘負(fù)離子開(kāi)成的二階碘化鈀負(fù)離子與質(zhì)子化乙醇形成電中性的締合物乙醇與二階碘化鈀負(fù)離子被乙醇相萃取，能使鈀(II)從鐵(III)、鋁(III)、鋅(II)、錳(II)、錫(II)、鉻(III)、鈷(II)的混合溶液中分離。該體系萃取分離鈀，與傳統(tǒng)的鹽酸-(β-巰基氫化肉桂酸異戊酯)-苯體系和liusuan-(β-巰基-β-苯丙酰苯)-三氯甲烷體系相比，具有不使用youdu溶劑、試劑用量少、分離成本低、分離迅速、操作簡(jiǎn)便等優(yōu)點(diǎn)。遼寧正規(guī)海綿鈀高價(jià)回收</p><p
