摘要
本文提出了一种测定空气中尿素粉尘含量的方法。将尿素粉尘吸收后转化为铵,通过测定铵含量间接得出尿素含量。本法具有较高的准确度与精密度。
A method for the determination of urea particulates in air is proposed in this paper.Urea particulates having been sucked up from the air are simultaneously converted to amine compound.The content of urea particulates is then measured indirectly by measuring the content of amine compound, This method is possessed of higher accuracy and precision.
