Due to the current severe air pollution,with sulfur dioxide as the main pollutant,it is prone to cause serious damage to the human body.In order to detect sulfur dioxide gas in the environment quickly and sensitively,a more sensitive and ef-fective InTPAPY-SA/HA composite hydrogel was successfully prepared,based on the designed and synthesized AIE probe and com-bined it with SA/HA hydrogel,which realized the detection of sulfur dioxide gas wish a mass fraction of over 0.125×10-6,and studred and calculated that the detection limit of 0.1×10-9 for the mass fraction of sulfur dioxide gas.At the same time,the devel-oped portable detection device was used to measure the hydrogel color and convert it into digital RGB value.The portable AIE gel detection device could realize the detection of sulfur dioxide in various occasions.
