potassium silicate solution used in zinc-rich water-base coatings was prepared by adding the nanosize SiO2 to the low molar ratio potassium silicate solution, and its microstructure was investigated... molar ratio potassium silicate solution is the bonder of zinc-rich inorganic coatings with excellent property. 关键词:nanosize SiO2; high molar ratio; potassium silicate solution; zinc-rich coatings......
-imidazoline) in presence of bacteria. Two types of bacteria, Corynebacterium- diphtheriae-intermedius (CDI), and Pseudomonas aeruginosa (PA), were used. The collector-bacteria interaction was characterized by Fourier transform infra-red (FTIR), frothing height and Zeta potential. The results show that the collector-bacteria interaction improves the flotation selectivity. Although, the PA positively......
