In-situ experiments were conducted to study the adsorption isotherms of ClO<inf>4</inf>&#x2212; and NO<inf>3</inf>&#x2212; onto 6 kinds of activated carbon(25&#x00B0;C). The results shows adsorption capacity of GAC is bigger than PAC, and may have some relationship with the iodine value of carbon. Competition adsorption exists between NO<inf>3</inf>&#x2212;(More)
Considerable amount of bromate were observed during UV irradiation in free chlorine solutions containing bromide, whereas much less were formed in UV catalyzed chloramine solutions containing bromide. Assuming that free bromine is the key intermediate of bromate, a simple model is developed to predict bromine species profiles either in UV catalyzed free(More)
In this paper, the emergent treatment for raw water from upper-reach of Huangpu river polluted by phenol was studied through small scale and pilot experiments. The removal capacities for volatile phenol of individual coagulation, individual powdered activated carbon (PAC) adsorption and PAC adsorption-flocculation process were examined, and the optimum(More)
