The adsorption of 2-phosphonobutane-1,2,4-tricarboxylic acid (PBTCA) on Al 2 O 3 powder has been studied as a function of pH and concentration. The adsorption density of PBTCA is found to decrease with an increase of pH. Zeta potential measurements show that the addition of PBTCA results in a dramat
