(
BioMed Central
, 2016 , Article)
Background
Soil contamination and associated pollution plays a detrimental role in soil flora and fauna. Soil is processed and remodeled by subterranean earthworms, accordingly are referred to as soil chemical engineers. ...
Mechanism and kinetics of electrochemical degradation of uric acid using conductive-diamond anodes
(
Taylor & Francis
, 2016 , Article)
Uric acid (UA) is one of the principal effluents of urine wastewaters, widely used in agriculture as fertilizer, which is potentially dangerous and biorefractory. Hence, the degradation of UA (2,6,8-trihydroxy purine) in ...
