Potentiometric Electronic Tongues: New Sensor System Applied in Environmental Monitoring
نویسندگان
چکیده
This work investigates the use of electronic tongues for environmental monitoring. Electronic tongue was based on arrays of potentiometric sensors plus a complex data processing by artificial neural networks. Special attention was paid in compensating temperature effects and possible drifts in the sensors response. In addition, and to demonstrate viability of the proposed systems for automated remote applications in environmental monitoring, the use of data transmission by radio frequency has been tested.

متن کاملPotentiometric Method to Determine Montelukast Sodium in its Tablets with In-line Monitoring of its Dissolution Behaviour
Direct drug determination without any pervious treatment steps is the most environmentally friendly method of analysis. Traditional analysis methods usually involve a pre-treatment step before analysis and this consumes time and organic solvents. This work describes direct potentiometric method by using ion selective electrode to determine Montelukast Sodium in its pure drug substance and in ta...
