According to the characteristics of the 9 types of surfactants, 7 kinds of them were selected for deinking test. 5 kinds of them with good effect were selected to compound. The optimized compounded formulation 3 was pickup for orthogonal experiment with different technical conditions. The optimized technical conditions was found to be A3B2C1D3, which is concentration 9%, deinking agent 0. 8%, deinking temperature 50 ℃, and deinking time 50mins. After deinking, the whiteness of the newspaper pulp reaches as high as 56. 1%.
