说明

一般說明

方法：试纸条和试剂比色法，0.02 - 0.05 - 0.1 - 0.2 - 0.5 mg/L As, 0.1 - 0.5 - 1.0 - 1.7 - 3.0 mg/L As, MQuant^®

砷试纸条适用于测定水、药品、制备的生物标本和液体食品中的砷。在此MQuant^®砷试纸中，试纸条需与其他试剂结合使用。通过添加锌粉（一种固体酸）和一种用于消除干扰性硫化物离子的氧化剂，可以从样品中释放出砷。在试纸的反应区上，会形成黄棕色染色。通过目视比较试纸条的反应区与比色卡的各色块，可半定量测定三价砷（III）和四价砷（V）浓度。试纸非常适合经济、快速地预测样品，以便在使用定量方法（例如Spectroquant^®试纸）前估算砷浓度和可能的稀释度。

應用

• Arsenic Pigments in Libraries – Testing Methods, Contaminated Spaces, and Occupational Safety Measures: In a research project, the Bonn University and State Library and the Cologne University of Applied Sciences analyzed the handling of arsenic in library materials. Arsenic-containing pigments in library materials are a source of danger for institutional staff, conservators, scientists, and users. Over 300 volumes with suspicious green book components were analyzed using both XRF and Raman spectroscopy, with arsenic compounds being detected in around half of them. The XRF device is mobile and effective, it yields reproducible data and can detect a multitude of elements such as arsenic, lead, and mercury. However, it emits radiation and is limited to small spots. Special training for operating the device as well as for interpreting the results is needed. A rapid test based on bromide test strips and the [TM=“MQUANT”] test kit were then evaluated. When comparing the rapid test kits, the [TM=“MQUANT”] test kit appears to be more suitable than the bromide test paper as it includes all necessary accessories and helps minimize the hazard potential for users. The [TM=“MQUANT”] test kit may be suitable for initial in situ examinations, after training and instruction of the archive staff, being fairly accurate, ready-made, easy to handle, and suitable for testing surfaces.
