DETECTION AND IDENTIFICATION OF CHEMICAL AGENT USING ATOMIC ABSORPTION SPECTROPHOTOMETER

Saradhi Nimmagadda, Asa Jyothi

Abstract: The problem comprises the automatic detection and identification of a vapour state chemical agent. Chemical agent in vapour state is being complicated in comparison with the agent in solid and liquid state. Actually the agent in vapor state being a mixture with the other agents like dust, water molecules and the other chemicals or gases in air .There are many techniques existing for the chemical agent detection but each has got its own parameters sensitivity ,calibration, accuracy etc. In this work atomic absorption Flame Spectrophotometer for detection is used due to its advantages with the sensitivity and calibration. 8051 microcontroller is used for the controlling and processing of system

Keywords: chemical agent detection, atomic absorption spectrophotometer
