Abstract：Three amphiphilic CTS were used for PosiDAF algal removal experiment, and the algal removal effects under different conditions were compared to explore the algal removal mechanisms. The results showed that the amphiphilic modification can enhance the water solubility of CTS while reduce the thermal stability of CTS. The significant degree of influence on the responding value (substitution degree) was as follows:carbon chain length>reaction time>reaction temperature>raw material feeding ratio. When the 1.0mg/L N-2hydroxypropyl trimethyl chitosan ammonium chloride (C4-HTCC) was used as modifier, the effectiveness of algae removal was the best, reaching 93.47%; because the modified microbubbles have strong electrostatic attraction.
