Title:
SYSTEM AND METHOD FOR DETECTING METAL IN SOLUTION
Document Type and Number:
WIPO Patent Application WO/2014/038191
Kind Code:
A1
Abstract:
Provided is a system whereby a metal ion in a solution is easily detected at a high accuracy. The system comprises: a unit (20) for mixing a first solution (21) containing a first organic compound that has affinity to the metal ion to be measured with a second solution (22) of the measuring object to give a mixed solution (29) and then supplying the mixed solution to a container (17); and a unit (10) for detecting the aforesaid metal ion in the second solution on the basis of spectra measured by ionizing a gas (19) in a head space (18) of the container. An example of the first organic compound is a siderophore (forming a complex with iron ion) such as catechol or AHA. The unit for detecting the metal ion concentration is an ion mobility sensor whereby the metal ion concentration in the solution can be detected in real time.
