ISLAMABAD: Iranian researchers from Materials and Energy Research Center (MERC) proposed a solution to measure the desired species in liquids by using XRF device.
Medical, foodstuff and environmental industries can use the results of the research to measure and detect the samples and control the quality of products, Fars news agency reported.
XRF device is a very powerful tool in detection and measurement processes, which is usually used on solid samples.
The aim of the research was to expand the application of the device.
In the research, the objective was to extract and measure vitamin B12 from liquid samples. To this end, the vitamin was extracted from the media by using graphene oxide.
Then, the sample was introduced to XRF device after placing graphene oxide on a filter.
According to the researchers, since vitamin B12 has a cobalt atom in its structure, the tracing of cobalt concentration in vitamin can be considered as a sign of the concentration of the vitamin itself.
Results showed that the proposed method has good accuracy, linear range and low detection limit.
The method is also quick, simple, and sensitive and it enables the extraction of vitamin B12 from a large quantity of thin samples.
