一种检测高纯勃姆石中杂质元素含量用的消解罐
本技术涉及消解罐设备领域,特别是一种检测高纯勃姆石中杂质元素含量用的消解罐。
技术介绍
勃姆石又称软水铝石,以其独特的化学、光学、力学性质在陶瓷材料、复合材料、表面防护层材料、光学材料、催化剂及载体材料、半导体材料及涂料等领域得到广泛的应用。目前高纯度的勃姆石在制备过程中仍会含有少量杂质,需要对其进行杂质元素的含量进行测量。由于勃姆石在常温常压下属于难溶物质,对其测量其各元素含量时,需要在酸性条件下高温水解形成溶胶质,再用原子吸收分光光度计法与电感耦合等离子体发射光谱法测量。如中国专利CN106168552A公开了一种测定勃姆石中元素含量的前处理方法:首先,精确称取一定量的勃姆石于容器中,加入高纯度的浓磷酸,使其与容器中的勃姆石充分接触;其次,加热煮沸至被浓磷酸浸泡的勃姆石完全溶解;然后,将勃姆石溶解后的溶液冷却稀释定容,得到勃姆石溶液;该方法操作过程简易方便、处理步骤较少、所需设备成本低、而且前处理过程对设备无损伤;该前处理过程仅使用了高纯度的浓磷酸,减小了外源物质的干扰,很大程度上降低了测定勃姆石中铝元素含量的操作难度,同时提高了分析结果的准确性。但是类似上述专利的测量方法存在以下不足:1.使称样量必须足够低一般为0.1-0.2g,勃姆石样品粒度必须足够细,否则勃姆石难以完全溶解,另外高纯勃姆石由于杂质含量低,称样量太低的话,不在原子吸收分光光度计法与电感耦合等离子体发射光谱法测量范围内,测量精度低;2.使用的磷酸在用移液管抽取过程中容易 ...
