Abstract

The chemical properties of fly ash and FAZ (synthesized zeolite made from fly ash) were studied by XRD. The results from this study showed that quartz and mullite were the main composition of fly ash and FAZ was a single-kind zeolite with residual unreacted fly ash. Moreover, the effects of FAZ diameter, dosage and contact time on the removal SO₄^2- from monosodium glutamate wastewater were analyzed. And L₉(3⁴) orthogonal table were made in order to determine the optimal factor level combination in the removal of SO₄^2-. It was strongly suggested that the removal ratio of SO₄^2- could reach 67.3% when FAZ dosage was 20 g/L, contact adsorption time was 60 minutes and adsorption temperature was room-temperature, and it was appropriate to select 100 mesh as the removal ratio and economy were comprehensively considered.
