如果可以通过印刷指示剂来制造纸基分析装置（mu-PAD），用于以元素周期表的形式检测金属化学符号中的重金属，那么这种mu-PAD就可以通过短信同时报告水中重金属离子的存在和安全水平。该设备将为工业废水排放以及灌溉和饮用水中的重金属现场监测提供简单的解决方案。即使非专业用户也可以通过文本报告及时了解水质情况。这项工作提出了这一想法的概念验证研究。选择 Cu(II)、Ni(II) 和 Cr(VI) 来证明纸质文本报告装置用于监测水中重金属的可行性、特异性和可靠性。
If a paper-based analytical device (mu-PAD) could be made by printing indicators for detection of heavy metals in chemical symbols of the metals in a style of the periodic table of elements, it could be possible for such mu-PAD to report the presence and the safety level of heavy metal ions in water simultaneously and by text message. This device would be able to provide easy solutions to field-based monitoring of heavy metals in industrial wastewater discharges and in irrigating and drinking water. Text-reporting could promptly inform even nonprofessional users of the water quality. This work presents a proof of concept study of this idea. Cu(II), Ni(II), and Cr(VI) were chosen to demonstrate the feasibility, specificity, and reliability of paper-based text-reporting devices for monitoring heavy metals in water.
