Enter the total amount of substance after purification and the original amount of substance before purification to calculate the percent recovery. This calculator can also evaluate either the amount of substance before or after the process if the other values are known.
Percent Recovery Formula
The following equation is used to calculate the percent recovery from a purification process.
PR = SAP / SBP *100
- Where PR s the percent recovery
- SAP is the substance amount after purification
- SBP is the substance amount before purification
To calculate the percent recovery, divide the substance amount after purification by the substance amount before purification.
The most important aspect of the calculator above is that the units of the substance amount must remain the same for an accurate calculation.
Percent Recovery Definition
Percent recovery is a term most used in chemistry to describe the amount of recovered substance after a purification process. This purification process could be anything from removing a chemical or separating a specific chemical entirely.
Percent Recovery Example
How to calculate percent recover?
- First, determine the substance amount before purification.
Measure the mass of the substance before purification.
- Next, determine the amount of substance after purification.
After purification, measure the total mass.
- Finally, calculate the percent recovery.
Using the formula above, calculate the percent recovery.
Percent recovery is a measure of the amount of substance that was recovered after a chemical reaction or purification process.
