1. Formation of DS-fixing agent PEC highly depends on the DS components, fixing agent molecular weight and its dosage, as very different phenomena can be seen in this study for different DS components, for polyamines with different molecular weight, and for the same polyamine used at a different dosage.
2. For fixing agent with enough low molecular weight and at enough low dosage, it can form loose and dispersible DS-fixing agent PECs, and increasing its dosage will produce denser and smaller PECs; for fixing agent with enough high molecular weight, it can directly form dense DS-fixing agent PECs, and increasing its dosage mainly increases the size of PECs; for fixing agent with medium molecular weight, its behaves between the two cases described above.
3. Although hemicelluloses modeled DS water showed that a small part of PECs formed are detectable by FBRM, the performance of DCS water 2 used in this study showed that DS-fixing agent PECs alone are generally too small to be detected by FBRM.
4. Based on the performance of DCS water 1 and DCS used in this study, it can be concluded that small CS particles undetectable by FBRM can be the “seeds” for producing larger particles detectable by FBRM, either by agglomerating the small CS particles or by depositing DS-fixing agent PECs onto the small CS particles. For the formation of FBRM-detectable particles, the agglomeration of medium sized CS particles (between 125nm-470nm in this study), or deposition of DS-fixing agent PECs onto such particles, seems critical.
