Hey guys, I am a student who is trying to investigate on the p-anisidine value (AnV) of biodiesel (fatty acid ester); however, in my school there isn't a uv-vis spectrophotometer, but just a vis spectrophotometer from 380nm to 700nm. Therefore, I can't really measure the absorbance of the biodiesel at 350nm. Is there any way that I could find the p-anisidine value ?
