Abstract
Purpose
The binary competitive effect could obviously influence the fate and transport behavior of oxytetracycline (OTC) and cadmium (Cd2+) in cinnamon soil. However, two pollutants loading into soil usually are different, perhaps because of the three reasons including occurrence of OTC before Cd2+, simultaneous occurrence of OTC and Cd2+, or occurrence of Cd2+ before OTC. The purpose of the study was to predict the competitive adsorption and desorption of OTC and Cd2+ as a function of above input loadings on cinnamon soil.
Materials and methods
Adsorption and desorption were determined using the batch equilibrium method in a single or binary system. The Freundlich equation was applied to describe the adsorption/desorption data of OTC and Cd2+ in order to obtain adsorption/desorption isotherms for each tested compound and the respective adsorption/desorption coefficients.
Results and discussion
The results indicated that cinnamon soil could strongly adsorb OTC with the adsorption affinity (K f value) of more than 718 and Cd2+ with K f value of more than 536 in the competitive and non-competitive system, and all adsorption and desorption isotherms of OTC and Cd2+ on cinnamon soil were well fitted by the Freundlich equation with r value of more than 0.99 (p < 0.01). The coexistence of OTC and Cd2+ on cinnamon soil promoted significantly Cd2+ adsorption when Cd2+ firstly or simultaneously occurred on soil, but their coexistence did not affect adsorption of OTC when OTC firstly or simultaneously occurred on soil. Among the three input loadings, the pollutant with later occurring mode had lower K f and hysteresis coefficient (HI) than the other two input loadings. According to the adsorption intensity parameter (1/n), the presence of Cd2+ or OTC with different input loadings could decrease the adsorption intensity of OTC or Cd2+ when compared with single occurrence of OTC or Cd2+.
Conclusions
The binary competitive effect influenced the adsorption/desorption of OTC and Cd2+ differently. The presence of OTC had a stronger influence on the adsorption/desorption of Cd2+ than the presence of Cd2+ on the adsorption of OTC. The later occurring pollutant on soil had stronger ecological risk than the former occurring pollutant in the binary competitive system. The physical adsorption in the single or binary system could be identified as the dominant mechanisms of OTC and Cd2+ adsorption.
