在首飾佩戴和收藏過程中要注意如下幾項：①佩戴貴金屬首飾，特別是在佩戴細小的款式新穎的手鏈和項鏈時更要引起注意，例如在穿、脫衣服或整理頭發(fā)時，可能會掛斷首飾或使首飾變形。②入睡前，應盡量取下首飾，以免首飾變形或折斷造成不必要的損失。③黃色貴金屬首飾不要與白色貴金屬飾品存放于同一首飾盒中，如黃金首飾不要與鉑首飾、鈀首飾、銀首飾存放在一起，因為它們會互相摩擦，造成顏色上的混染。④足金、足鉑、足銀首飾不要與低含量的飾品置于同一首飾盒中，以免造成含量上的互相混染。⑤首飾戴久了表面往往失去光澤或顯得很臟，這時可以到有關商場首飾柜、黃金珠寶專賣店或有信譽的首飾加工店去拋光、清洗或電鍍，他們配備了超聲波清洗儀，都有這方面的售后服務。也可自己用絨布、麂皮等干擦，或用酒精、洗滌劑、清水擦洗或濕擦。⑥避免接觸醋，果汁，漂白劑，涂改液等物質(zhì)，以及含鉛汞等元素的化學品。⑦比較好在化妝完畢后再佩帶首飾飾品，這樣可以避免香水、化妝品、噴發(fā)劑等物質(zhì)對飾品造成的損害。

貴金屬首飾包括各種發(fā)飾、白金首飾耳飾、頸飾、手飾、足飾、服飾等。如何正確佩戴這些首飾則是一門藝術，這門藝術給人們的生活增添了無窮的樂趣與色彩，它可以賦予人們鮮明的時代感，給人們一種精神享受；它可以豐富生活的內(nèi)容，創(chuàng)造一種和諧的美。當人們贊賞某人佩戴的首飾很美時，這種贊美往往包含著三種含義：一是指這種首飾本身從色彩、款式、設計風格和做工確實都很美；二是指這種首飾與佩戴者的特點十分吻合，它能掩蓋缺點，突出優(yōu)點，盡顯佩戴者的美麗；三是指這種首飾能增添佩戴者的美麗，它在佩戴者的整體形象中起到了畫龍點睛的作用，烘托出了一種氣氛、一種情調(diào)、一種風格。

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溶劑作萃取溶劑，有的反應速度慢，傳質(zhì)速率低，分配比較小而需要在振蕩器上進行較長時間振蕩或多次萃取才能達到定量萃取的目的。均相萃取、異相分離萃取體系可以克服異相萃取分離技術中的一些缺點而受到重視。本文以乙醇為萃取溶劑，均相萃取、異相分離Pd(II)。試驗表明liusuan銨存在下乙醇與水分相過程中，鈀(II)與碘負離子開成的二階碘化鈀負離子與質(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、操作簡便等優(yōu)點?？诒孟跛徕Z詢問報價</p><p
