5I言

纳米复合镀层材料是目前七大类纳米复合材料之一,在材料表面防护和改性等方面B出

现前所未有的广泛的应用前景n。】。在纳米复合镀的工艺研究中。镀层中纳米微粒共析量犬小

的确定十分重要,目前的测定方法基本采用重量法或表面能谱分析法(如,EDX、XPS等)[I.“。

重量法测定复合镀层中纳米微粒共析量的工艺是:首先将镀层溶于酸后得到含纳米微粒

的溶解液(其中的纳米微粒含量多在几十个一几百个ppm),经多次清洗、分离和干燥后称重得

到共析量的大小。由于纳米微粒悬浮性很强,在多次清洗、分离过程中难免丢样,会带来较大的

实验误差.甚至无法测定。而且还存在操作工序多、费时等缺点。

表面能谱分析法属于半定置的分析方法,测定误差较大,对于纳米微粒分布并不均匀的复

合镀层,这种微区分析法带来较大程度的随机性,若测定点不是足够多,测定误差会很大,而多

点测定费时较多,导致昂贵的测试费用。另外,表面能谱分析法所用仪器极其昂贵,使其应用受

到很大限制。

本研究针对现有重量法及表面能谱分析法的缺点,提供一种采用常规仪器紫外一可见分

光光度计分析复合镀层中纳米微粒含量的测定方法嘲。本文主要介绍纳米Al。o。复合镀层经

溶解得到的酸性纳米溶液中纳米Al:O。的测定方法及实验结果,并将本方法与重量法及表面

能谱分析法进行对比。

由表2一表3可见,当溶液中纳米微粒含量很低时,重量法几乎难以应用;紫外分光光度

法的相对误差及偏差均远远小于重量分析法;另外,重量分析法也很耗时,一般一个样品测定

需要两天时间(静置沉淀约需一天时间),而紫外可见分光光度法从配液到测定完毕需要时间

不足一个小时。

4结论

(1)纳米Al:o,酸性溶解液中(pH=1的HNO,溶液、pH=l的NiSO・一HNOs溶液、pH=

1的cusO。--HNO:溶液、pH=i的ZnSO。--HNO。四种空白溶液)均存在空白液吸光度很低,

工作液吸光度较高的较大的波长区间,这些体系是分光光度分析法中理想的测定体系,其特征

吸收波长为z00—800nm、430一620nm、350一600nm、340一800。

(2)上述体系的标准曲线线性都十分理想,其相关系数均大于0.98。

(3)紫外分光光度法的平均相对误差(2.15X)远远小于重量分析法(98.23%),且比重量

分析法(两天时间)省时(小于一小时)。

由表2一表3可见,当溶液中纳米微粒含量很低时,重量法几乎难以应用;紫外分光光度

法的相对误差及偏差均远远小于重量分析法;另外,重量分析法也很耗时,一般一个样品测定

需要两天时间(静置沉淀约需一天时间),而紫外可见分光光度法从配液到测定完毕需要时间

不足一个小时。

4结论

(1)纳米Al:o,酸性溶解液中(pH=1的HNO,溶液、pH=l的NiSO・一HNOs溶液、pH=

1的cusO。--HNO:溶液、pH=i的ZnSO。--HNO。四种空白溶液)均存在空白液吸光度很低,

工作液吸光度较高的较大的波长区间,这些体系是分光光度分析法中理想的测定体系,其特征

吸收波长为z00—800nm、430一620nm、350一600nm、340一800。

(2)上述体系的标准曲线线性都十分理想,其相关系数均大于0.98。

(3)紫外分光光度法的平均相对误差(2.15X)远远小于重量分析法(98.23%),且比重量

分析法(两天时间)省时(小于一小时)。
