摘要
以氨基磺酸为显色剂，用分光光度法测定燃料油中硅含量。考察了测定条件：在酒石酸及硫酸介质中，最大波长位于815nm，二氧化硅浓度在0—250μg范围内符合比尔定律，线性关系较好。实验结果显示，该方法适用于燃料油中硅含量的测定，结果满意。
A new method of determining silicon in fuel oil with spectrophotometry was studied. Silicon in fuel oil reacts with aminosulfonic acid and form a violet component in the medium of tartaric acid and sulfuric acid . The component exhibits maximum absorption at 815 run .Beer＇s law is obeyed in the range of 0 - 250 μg for silicon dioxide and linear correlation is better. The result indicated that the method has been satisfactorily applied to the determination of content of silicon in fuel oil.
