acidity constant

The acidity constant ( pATa) of a metabolic uncoupler highly influenced its effectiveness in sludge reduction, i.e. metabolic uncoupler with a lower pKa value has a higher potential to reduce sludge production which confirmed the theoretical analysis that uncoupler weaken the proton motive potential producing ATP.

各种代谢解偶联剂效果的差异与其酸性大小有关，pKα值越低，污泥的减量化效果越好，这证实了解偶联剂所造成的产生ATP质子动力势（pmf）弱化的理论分析。
