Application of biosurfactant tea saponin in flotation separation for ternary plastic mixtures : statistical optimization and mechanism analysis

Plastics flotation is facilitated to the sustainable development and cleaner production of the industry. Biosurfactant tea saponin was first applied to a flotation process for ternary plastic mixtures so as to minimize the secondary pollution. Response surface methodology was utilized to optimize su...
