I am currently doing a research project, and for it, I would like to use a photospectrometer to find the concentration of Calcium Perchlorate in my sample solutions. My current method of data collection relies on using an indicator (methalyne blue) to form a purple precipitate to observe under a microscope as a qualitative means to collect data, but if I can use a spectrophotometer (96 well) to directly measure absorbance and in turn concentration, that wold be heavily preferred.
How would I be able to find out what specific wavelength I need to measure for my Calcium Perchlorate? I can't find any preexisting values online for Calcium Perchlorate, so any help would be greatly appreciated. Thank you!
