文摘

The aggregation/retention of nTiO2 is stronger in single NH4+ than that in Na+. The enhanced transportability of nTiO2 in binary system of Na++NH4+. Two-site kinetic retention model provides good simulation for transport in NH4+. The reversible retention of nTiO2 in NH4+ is related to K2 on Site 2 from model.
