摘要

正

Dilute solution behavior of chitosan was studied in formic acid

acetic acid

lactic acid andhydrochloric acid aqueous solution under different pH values. The reduced viscosities

ofchitosan solutions were dependent on the properties of acid and pH value of solvents. For a givenchitosan concentration

/C decreased with the increase of acid concentration

or decreasing pHof solvent

indicating shielding effect of excessive acid similar to adding salt into solution. Thestabilities of dilute chitosan solution in formic acid and lactic acid were better than that in acetic acid and hvdrochloric acid.
