The present work describes a simple and reproducible direct-read system for onsite monitoring of beryllium on surfaces of work areas. It is based on the colorimetric reaction of beryllium with active ingredients deposited in a swab. A color comparator consisting of beryllium color chart was designed to enable the semi-quantitative determination of beryllium in surface samples. The system provides a minimum detection limit of 0.01 microg sample(-1). Metals tested for any interference effect include Al(3+), Ba(2+), Cd(2+), Cu(2+), Co(2+), Cr(3+), Cr(6+), Fe(3+), Hg(2+), Mg(2+), Ni(2+), Pb(2+), Ti(4+) and UO(2)(2+). Validation of the system showed no significant effect from metal interferences on the quantification of beryllium.
本研究描述了一种简单且可重复的直接读取系统，用于对工作区域表面的铍进行现场监测。该系统基于铍与拭子中沉积的活性成分的比色反应。设计了一个由铍比色卡组成的颜色比较器，用于对表面样品中的铍进行半定量测定。该系统的最低检测限为0.01微克/样品。测试的可能产生干扰效应的金属包括Al(3+)、Ba(2+)、Cd(2+)、Cu(2+)、Co(2+)、Cr(3+)、Cr(6+)、Fe(3+)、Hg(2+)、Mg(2+)、Ni(2+)、Pb(2+)、Ti(4+)和UO(2)(2+)。系统验证表明，金属干扰对铍的定量没有显著影响。
