Several authors have found that comminut, ground or powdered shell material has very high heavy metal sorption capacities, which are similar to, or can even exceed those of chitin, chitosan and other sorbent materials (Tudor 1999; Kim and Park 2001; Petrisor et al. 2002; Rae and Gibb2003; Tudor et al. 2006; Köhler et al. 2006; Ok et al. 2010; Yan-jiao 2011). Shell material has also been used to remove dye (Figueiredo, et al. 2005) and reclaim waste lubricating oils (Osakwe and Maduako 2004).
