Analysis of Phosphate in Wastewater Using an Autonomous Microfluidics-Based Analyser
نویسندگان
چکیده
A portable sensor for the analysis of phosphate in aqueous samples has been developed. The sensor incorporates microfluidic technology, colorimetric detection, and wireless communications into a compact and rugged portable device. The detection method used is the molybdenum yellow method, in which a phosphate-containing sample is mixed with a reagent containing ammonium metavanadate and ammonium molybdate in an acidic medium. A yellow-coloured compound is generated and the absorption of this compound is measured using a light emitting diode (LED) light source and a photodiode detector. The absorption is directly proportional to the phosphate concentration in the original sample. In this paper we describe the application of this phosphate sensor to the analysis of wastewater at a municipal wastewater treatment plant in Co. Kildare, Ireland. Keywords—Microfluidic, phosphate, sensor, wastewater.

Monitoring of Phosphate Levels in Wastewater Using an Autonomous Microfluidic Sensor
An autonomous sensor for monitoring phosphate levels in aqueous samples has been developed. The sensor is based on the molybdenum yellow method for detection of phosphate, which involves the formation of a yellow-coloured compound when a phosphate-containing sample is mixed with an acidic reagent containing ammonium molybdate and ammonium metavanadate. The reaction is carried out in a microflui...
متن کاملValidation of a fully autonomous phosphate analyser based on a microfluidic lab-on-a-chip.
This work describes the design of a phosphate analyser that utilises a microfluidic lab-on-a-chip. The analyser contains all the required chemical storage, pumping and electronic components to carry out a complete phosphate assay. The system is self-calibrating and self-cleaning, thus capable of long-term operation. This was proven by a bench top calibration of the analyser using standard solut...
