水质硫化物测定中吹气装置改进探索

Researches on the improvement of blowing device for determining sulfide in water

用改进的硫化物吹气装置进行了温度、气速、时间等因素对回收率的影响试验 ,证明改进的硫化物吹气装置具有回收率高、省时、温度低等特点 。

Effect of the factors such as temperature,airflow and time on recovery ratio has been tested by using the improved blowing device. It shows the recovery ratio is high,the time is short and the temperature is low,proving the new device is successful.
