The lecturer Baseem Hafeez Fadhil and the lecturer Dr. Nada Naoum Abdul Razzaq from the department of chemical engineering at the University of Baghdad have manufactured a low-cost visible-light spectrometer for measuring dyes concentration in the liquid state used in many different technical and engineering applications.
The optical spectrometer is usually available in postgraduate laboratories where it requires good training to be used by scholars and sometimes a supervisor to make the measurements properly since it is relatively an expensive device. The inventors sought to provide an easy-to-use educational tool for postgraduate students to comprehend the concept of light and how it overlaps with chemicals when measuring some known dyes that simulate the advantages provided by the commercial spectrometer at a cost of less than fifty dollars using 3D printing technology and some other electronics available in our local markets. The researchers also elected specific dyes like Methyl red and Methyl orange as models to examine the quality of the proposed spectra in terms of accuracy, repeatability and sensitivity as compared to a conventional measurement. The findinds showed a very high accuracy in measurement that can be relied on by future studies thus the study was published in the Iraqi Journal of Chemical and Petroleum Engineering issued by the college of engineering.
