A preparation method of formaldehyde removing agent

A preparation method of formaldehyde remover and belongs to the remover production technology of eliminating the harmful gases in the environment. Mix the prepared releasing agent and chlorine dioxide water solutions in a certain proportion to produce formaldehyde remover, the steps are: absorb the gas of more than 90%chlorine dioxide purity with the aqueous solution of 13 percent sodium carbonate concentration to form a stable state of chlorine dioxide solution. The releasing agent was mixed by analytically pure or chemically pure solid acid and salt and the proportion of volume of chlorine dioxide aqueous solution to the weight of release agent is 10 to 0.2 to 0.3. The beneficial effects of the invention are: (1) the released chlorine dioxide gas can rapidly oxidize formaldehyde in air without secondary pollution; (2) the remove rate to formaldehyde is up to 90 percent.
