When GB was at a relatively high concentration (≥1.0 mg/m 3 ), the response signals of the SAW-SXFA sensor showed an increasing trend with the increase in the GB concentration within the same time period, which conformed to the law of solid adsorption isotherms [ 25 ], and the SAW-SXFA sensor could recover more than 65% of the response signal.
