Abstract EN
Effects of experimental conditions on the yield of extracellular polymeric substances (EPSs) extraction by cation exchange resin (CER) were investigated using activated sludge flocs.
The experimental variables included resin dose, extraction time, sample dilution, and storage time.
An empirical model was proposed to describe the kinetics of extraction process.
The extraction yield increases with the extraction time and CER dose until it reached the maximum amount of EPS extraction.
The maximum yield of EPS was affected as well by the sample dilution, exhibiting a decreasing trend with increasing dilution factor.
It was also found that the amount of EPS extracted from a raw sample depends on the storage time.
Once EPS was extracted from the sample, however, the EPS keeps its original quantity under storage at 4°C.
Based on the model, the maximum amount of EPS extraction and yield rate could be estimated for different conditions.
Comparing the model parameters allows one to quantitatively compare the extraction efficiencies under various extracting conditions.
Based on the results, we recommend the original sample should be diluted with the volume ratio of above 1 : 2 and a raw sample should be treated quickly to prevent the reduction of sample homogeneity and original integrity.
