【摘要】 针对排放烟气汞浓度在线测量系统中汞的吸收系数,基于饱和蒸气原理的光谱法在线测量汞气浓度,并在500-2500μg·m^-3浓度区间进行了实验。初步定量了室温下汞在253.65 nm上的吸收截面为1.423×10^-14cm²·atom^-1。更多还原

【Abstract】 Mercury emission on-line measurements have diffculty in qantification of atomic absorption cross-section.This study suggested a novel method based on saturated merucy vapor pressure dependent of temprature and mercury concentration between 500- 2500 μg·m^-3.Results indicated that mercury absroption cross section at 253.65 nm room tempreture is 1.423×10^-14 cm²·atom^-1.更多还原
