Summary: | Use of cyanide in developing countries is rampant, especially in gold mining areas. Though it could cause serious environmental problems, cyanide contamination is of less priority for government monitoring because of the limited resources. The current detection and monitoring schemes of cyanide are the conventional and expensive laboratory-based methods, which need technical capabilities to conduct the actual testing and preparing manual data recording, making it tedious and too laborious. More efforts were directed towards digitizing the data recording from manual laboratory analyses as the manual data recording usually cause problems like delayed information, lost data, and erroneous data entry. Hence, the goal of this study is to provide a cost-effective and zero manual-recording measurement method for cyanide in water samples. This work focuses on the design of electrochemical measuring devices with the same capability with the portable or benchtop-type of cyanide meter but with an automated and realtime data recording using global system for mobile communications (GSM) technology. Results of this study showed that with the existing GSM technology and infrastructure of the new monitoring system, the measurements are comparable to that of a commercial bench-type cyanide meter with an R-squared (R2) of 0.9907. It was also noted that data being recorded were intact during wireless transmission testing using the GSM Network. The results obtained suggest that wireless communication using GSM Technology could be applied to environmental monitoring. Importantly, the newly developed online system for cyanide monitoring offers significant advantages over the conventional techniques such as low-cost, easy deployment, and ease of use. It can increase spatiotemporal data for better analysis of the data. The automated data acquisition and display through cellular phones are also made readily-available. |
