I have taken a sample from a river contaminated with a drug Y in x amounts. I am using standard addition to quantify the amount of Y in the sample. I have added increasing amounts of Y (1-9) mg/ml to the water sample. The samples were filtered through 0.2 uM filter. The samples were undiluted. They were processed as received. Calculate the value of x to 5 decimal places.
Concentration (mg/mL) | Detector response |
0 | 1,1 |
2 | 1,2 |
3 | 1,4 |
4 | 1,5 |
5 | 1,6 |
6 | 1,8 |
7 | 1,9 |
8 | 2 |
9 | 2,1 |
