Abstract
In this paper, a method for the determination of formaldehyde in carbon-coated air purifying material by ultraviolet spectrophotometry was established. The test determined the detection limit, lower limit of determination, precision and accuracy of the method. When the sampling quality is 2.0g, the detection limit of the method is 0.0412μg, the recovery is 98.4%∼105.8%, and the precision RSD is 2.646% ∼ 3.894%. The results show that this method is suitable for the determination of formaldehyde in carbon-coated air purifying material.
