For Time Dependent Optical Density Measurements Using Colorimetry and UV-Vis Spectroscopy with Potential Dye Degradation Application, Performance Evaluation of Manganese Nanoparticles Functionalized by Syzygiumcumini Leaf Extract

Abstract

Aim:To analyze manganese nanoparticles functionalized by Syzygiumcumini leaf extract to obtain time dependent optical density (OD) measurements using colorimetry and UV-Vis spectroscopy for innovative dye degradation analysis of eosin yellow. Materials and Methods: Present study comprises of 2 sections, group 1 is colorimetry based OD and group 2 is UV-Vis spectroscopy based OD for the pretest power 80%, alpha=0.05 and enrolment ratio is 1. SPSS was used for performing independent sample T test and yield the statistical data. Results: Colorimetry mean OD was around 0.1865 and UV-Vis spectroscopy mean OD was 0.1093 with a p value of 0.001. Conclusion: Colorimetry seems to be significantly better than UV-Vis spectroscopy in measuring OD values of eosin yellow dye degradation produced by  manganese nanoparticles functionalized by Syzygiumcumini leaf extract
