摘要: The influence of cobalt speciation on the toxicity to methylotrophic methanogenesis in anaerobic granular sludge was investigated. studied with three different media that contained varying concentrations complexing ligands [carbonates, phosphates and ethylenediaminetetraacetic acid (EDTA)]. Three fractions (nominal added, dissolved free) were determined liquid correlated data from batch experiments. average concentration required for 50% inhibition methanogenic activity (IC50) free Co2+ sets measurements 13 μmol/L a standard deviation 22% similarity 72% between obtained range IC50 other two much higher, i.e. 85 144% added cobalt, respectively, almost 0% both fractions. Complexation (and precipitation) EDTA, carbonates shown decrease methanogenesis. is proposed be key parameter correlate toxicity. Thus, can estimated based equilibrium-free concentration.
