As an abundant bio-based renewable material, waste eggshell (WES) is useful to adsorb heavy metal ions from water, but its structure features and performance of reuse lack deep understanding. For the first time, based on scanning electron microscopy (SEM) study, fractal theory was applied to reveal the pore structure feature of waste eggshell and its self-similarity was described in terms of fractal dimension. Taking Cu(II) ion as a typical heavy metal ion, by experimental comparison, the used WES can be better regenerated by NaCl solution without adsorbent loss than by EDTA solution.
