The literature contains many investigations of each of and triply distilled H 2 O. the metals in question, Co (1)(2)(3)(4)(5)(6)(7)(8)(9), Ni (1, 4, 10-17), Cu (1,4,6,(16)(17)(18)(19)(20)(21)(22)(23)(24)(25), Cr (16,[26][27][28][29][30][31][32][33][34][35][36][37][38], but most of them do not 2.2. Analytical Methods compare adsorption and precipitation directly, and often the amount of dissolved alumina is not mentioned, nor is the pH measurements were executed with a glass electrode acid or base added during the experiment.…”
