The effects of feeding way of phosphorus pentoxide, ratio of C8H174OH to P2O5, reaction temperature and time on the synthesized isooctanol polyethenoxy ether phosphate were investigated. Its optimum synthesis technology conditions were as follows: feeding at batches while stirring tempestuously at 45℃, the ratio of nC8H17(EO4OH:n(P2O5)=2:1, esterifying at 70℃ for 4h, and add given volume of water at 70℃ for hydrolysing 2h.

The results of batch experiments showed that the anaerobic biodegradation kinetics of 2-CNB and 4-CNB by granular sludge were follwed by first-order reaction. The nitro groups of 2-CNB and 4-CNB were more easily attacked by electron than chlorines and they were reductively biotransformed to amino groups under anaerobic conditions. The acclimated anaerobic granular sludge, which could dechlorinate 4-chloroanline to aniline, showed that it had the ability of para-dechlorinating. The anaerobic biodegradating on pathway of 2-CNB and 4-CNB were suggested as follows:AbstractIn ZVI(zero-valent iron, Fe0)-reduction system, the nitro groups of 2-CNB and 4-CNB were reductively transformed to amino groups.
