摘要：

Progressive removal of particles from freshwater samples by filtration using various pore diameter polycarbonate capillary membranes (0. 4, 0. 1, 0. 05, and 0. 015 mu m) caused a reduction in the levels of labile aluminum (0-23%), as detected with pyrocatechol violet (PCV), in the filtrates. Removal of aluminum adsorbed onto suspended solids and aluminum losses through adsorption onto the membranes are thought to be responsible for these observations. Losses of aluminum during filtration of freshwater samples were evaluated by filtration of particle-free synthetic solutions and found to be less than 10%).
