I know the rate law. But for my photo-catalytic experiments, first 90min is adsorption (dark) and next 150min is under UV light (total 240min). How to remove the adsorption part for calculation? Can you describe with details?
Umar Arif Is it like this? Am I right?
Suppose my starting concentration is 10 ppm and after 90min of adsoprtion it came 8 ppm. After UV light from 91 min the conc. 6ppm 120min, 4pm 150min. In regular basis, we use to calculate the C/C0 is 8/10 for t90. 6/10 for t120, 4/10 for t120.
But now I have to consider first 90min is 0. So the initial concentration will start from 8ppm. and I have to calculate the C/C0 is 8/8 for t0 , 6/8 for t30, 4/8 for t60min. Am I right?
Md Tanvir Uddin Malik, when the ppm solution is in dark, that is ready for your degradation study, while the ppm stock solution will help you to calculate the difference between them. every time, after a specific time, when take reading just compare the value with the 1st one. while can study some of my research article i explain it in detail. you may contact me if you are still confuse.
Dear Md Tanvir Uddin Malik, if you need you can text me via email [email protected], i will very happy to explain you well the right procedure
