Abstract:

A soil remediation experiment was carried out with maidenhair (Tagetes patula)as phyto-remedifier, bacteria (phyllobacterium myrsinacearum)-fungi (Rhodotorula mucilaginosa) mixture solution as bacto-remedifier, and fertilizers (ammonia sulfate, calcium biphosphate and potassium chloride), organic acids (tartaric acid, oxalic acid, and citric acid) and chelating agents ( NTA and EDTA) as eight separate intensifiers, to treat a soil polluted with cadmium (Cd) and oxytetracycline together. In terms of the effect of intersifying Tagetes patula's enrichment of Cd, the eight intensifiers displayed a decreasing order of ammonia sulfate≈potassium chloride> EDTA> tartaric acid> oxalic acid> calcium biphosphate >NTA> citric acid >control, while in terms of the effect of intensifying degradation of oxytetracycline, fertilizers were on the top, followed by organic acids and wound up by chelating agents. And among the fertilizers, ammonia sulfate was the most effective in remedying Cd and oxytetracycline polluted soils.

Key words: cadmium, oxytetracycline, Tagetes patula, intensifying measure
