Abstract:In this article, we approach the subject about the methods of gathering samples in measuring the formaldehyde in the air. We gathered the formaldehyde in the air by using water and thin sulphuric acid solutions as absorbing solutions respectively. And the results of the experiments show that if we use the sulphuric acid solutionsn the concentration of which is 0.005 mol/L as the absorbing solution, we can prolong the reservation of the sample effectively and stably,and can fulfil the requirements of the accuracy and the precision of the method.
Keywords:formaldehyde  methods of gathering the samples  improvement
