- ... Imogolite, an aluminum silicate clay mineral obtained from volcanic ash soil, has several unique properties: a nano-tubular structure, having positive charge below pH 9, and coagulation beyond pH 6–7. Thus, imogolites can play an important role when volcanic ash soil-based coagulants are used for coagulation.To understand the mechanism of imogolite-induced coagulation and subsequent sedimentation, ...
