During the third quarter of 1993, we continued work on Tasks 2, 3, 4, 5, and 6. In Task 2, we tested the NO{sub x} sorption capacity of Fe(II)-EDTA and five new SRI-synthesized compounds. We also made a comparison of all the tests so far and have selected two compounds as the leading candidates. In Task 3, we electrochemically converted FE(III) phthalocyanine to its Fe(II) analog and synthesized several metal phthalocyanine compounds. In Task 4, we evaluated 200-fiber HFC modules for SO{sub 2} removal with water and solutions of Na{sub 2}SO{sub 3}. We also connected this HFC unit to the liquor regenerating HFC unit described in Task 6. We continue to observe 95--100% SO{sub 2} removal. In Task 5, we calculated the overall mass transfer coefficients of earlier Fe(II)-EDTA runs for scrubbing NO{sub x}. We also obtained a new module from Hoechst-Celanese and began its characterization. In Task 6, we demonstrated that the spent liquor from Task 4 can be regenerated using a second HFC. The spent liquor was regenerating using DMA with initial recovery of SO{sub 2} up to 52%.
