Electrolysis experiments were carried out with wheat straw soda black liquor with stainless steel (SS) electrodes. Electroactive lignin anions were found to form complex with the iron in the matrix of the SS anode surface to form a solid deposit. The deposits were examined with SEM and found to be in the form of irregular small granular mass. The granular solids so obtained were characterized with Energy Dispersive X-ray (EDX) analysis, TEM, XRD, and Selected Area Electron Diffraction (SAED) techniques. The electrodeposited lignin contained an unusually high iron to carbon atomic ratio. The granules varied in size from 1 to 1.5μm, with each granule itself made up of individual particles of different size and shape. The solids were amorphous in nature as confirmed by their XRD and SAED analyses.
