The investigated potassium carboxylates included: monocarboxylate potassium acetate, dicarboxylate potassium tartrate (K2Tart), tricarboxylate potassium citrate (K3Cit), and tetracarboxylate dipotassium of ethylenediaminetetraacetic acid (K2EDTA). KOAc can only induce calcium oxalate monohydrate, while K3Cit and K2EDTA induce COM and calcium oxalate dihydrate. The ability of multicarboxylates to induce COD formation was increased with increasing their concentrations.

PAM can induce the formation of calcium oxalate dihydrate crystals and change the morphology of COD and calcium oxalate monohydrate crystals.

PAM可以诱导二水草酸钙晶体生成并改变COD和一水草酸钙晶体的形貌。

Experimental results indicate that the reduction of chemical oxygen demand were 40%, 38%, 12%, 50%, and 73% for β-naphtho1, salt R, dihydroxy salt R, acid red, and wastewater, respectively when the reactions had run for 4 h at a pH of 1.7. In comparison, the COD reduction of-naphtho1 and salt R were 10.2% and 16.2%, lower than 23.4% and 18.1% with H2O2, while the Fenton reaction time was 1 h.
