ÔÚÕâÆªÎÄÏ×Colloids and Surfaces A: Physicochemical and Engineering Aspects Ìáµ½ÁË The polyanionic organic complexants like humic acids canmod- ify the surface charge properties ofmagnetite entirely or in a certain degree depending on their amount present in the systems. Since the trace amount of HA (0.08mmolHA/g magnetite) only neutralizes the positive charges of magnetite at pH lower than its PZC ∼8, and so it promotes the aggregation between the particles having both positive sites and negative humate patches on the surface [5]. This patch-wise surface charge heterogeneity ruins the colloidal stabil- ity of oxide dispersions considerably [26]. However, the presence of larger HA amount (1.64mmol/g roughly two times higher than the adsorption saturation of HA in Fig. 1, left) leads to the complete surface coverage causing a sign reversal of particle charge and over- charging of nanoparticles. High negative electrophoreticmobilities were detected over a wide range of pH from 3 to 10 proving the enhanced electrostatic stabilization due to the coating layer of HA. |
