Carbon release behaviour of polylactic acid/starch-based solid carbon and its influence on biodenitrification

The carbon release behaviour of polylactic acid (PLA)/starch blends and the correlation between solid-phase denitrification (SPD) performance and solid-carbon decomposition were investigated by both batch experiments and numerical simulations. The results showed that the mass ratio of PLA to starch is a key parameter in determining the total organic carbon (TOC) release rate of the blends. Hydrolysis of the blends contributed more markedly to...
