Iranian researchers from Shahid Beheshti University succeeded in the production of a sensor to detect heavy metals in samples with naked eye.
Detection of Heavy Metals in Samples with Naked Eye
Tehran, Iran | Posted on January 26th, 2015The application of this sensor enables the determination of the amount of metal ions in the sample in the place of the sample. It also eliminates the need for expensive and large laboratorial devices, and the transportation of the sample to the laboratory.
The necessity of simple and cheap detection of toxic ions is not deniable in a wide range of applications, including the management of industrial processes, foodstuff quality control, detection of chemical threats and environmental preservation.
In this research, polymeric nanocomposite containing titanium dioxide nanoparticles was designed as a very selective and sensitive dye sensor. The sensor is used for the detection of very small amounts of mercury and lead ions in local samples.
There are various analytical methods for the measurement of heavy metal ions, which are very accurate and have low detection limit. However, there are limitations for the application of these methods due to the use of large and expensive devices. The use of the designed chemical sensor based on color detection is very simple and it has very high sensitivity in the detection of heavy metal ions. In addition, the method does not require expensive devices due to the detection and characterization of ions by eyes.
The sensor can be used simultaneously in the detection and full elimination of metal ions in a wide range of concentrations.
The production of the sensor is simple and fast, and it can be used for the detection of ions due to the repeatability and accuracy of the sensor.
Results of the research have been published in Journal of Hazardous Materials, vol. 285, issue 1, 2015, pp. 109-116.
