摘　　要：对肇庆学院的两个地点进行对二氧化硫的采样测定,采用HJ 482-2009甲醛吸收——副玫瑰苯胺分光光度法。监测结果表明,两区校园内二氧化硫的浓度均低于0.15 mg/Nm^(3),达到国家标准的一级标准。校园区的空气二氧化硫浓度呈现有规律的日内变化:白天时,空气二氧化硫的浓度在早晨最高,并随着温度的升高而降低;傍晚后,空气二氧化硫的浓度随温度降低而再次升高。Sampling and determination of sulfur dioxide from two sites in Zhaoqing University were carried out by using HJ 482-2009 formaldehyde buffer——pararosaniline hydrochloride spectrophotometric method.The monitoring results showed that the concentration of sulfur dioxide in the campus of the two districts was lower than 0.15 mg/Nm^(3),which reached the first level of national standard.In the daytime,the concentration of SO 2 in the air was the highest in the morning and decreased with the increase of temperature.After evening,the concentration of sulfur dioxide in the air increased again as the temperature decreased.
