摘要

Sustained-release Sodium percarbonate has been dictates to oxidize a wide range variety to organic and inorganic compounds in underground water under multiple conditions of environment of contamination in groundwater.Sustained-release Sodium percarbonate is effective showed over a wide pH ranges.Even though the theoretical dosage of [PAHs]/[2Na2CO3·3H2O2] even down to 0.4 for complete decomposition degradation of PAHs,it still needed,at least,3 moles of [2Na2CO3·3H2O2] to decomposition degradation this chemical dosage.This indicates that oxidation intermediates competed sodium percarbonate molecules with the parent PAHs.The primary pH has no obviously efficacy on PAHs decompose,for hydrogen-ions were conformation during the period of PAHs decomposition.
