| Summary: | Pectic acid contained in some fruits like orange and apple is natural chelating polymeric material, exhibiting
excellent adsorption behavior for some cationic metal ions including toxic heavy metals such as lead and copper. In
addition, it also exhibits excellent adsorption behavior for some hazardous inorganic anionic species like
phosphorus, arsenic and fluoride by loading some high valence cationic metal ions like zirconium(lV) in advance.For
the practical application to the removal of these hazardous inorganic elements from various waste water at cheap
cost, orange juice residue was employed instead of pure pectic acid. Orange juice residue just after juicing was
activated by saponification with small amount of calcium hydroxide to prepare the sorbent.Somehazardous cationic
species like lead(II), copper(lI) and cadmium(lI) were effectively adsorbed.on this sorbent, while toxic anionic
species like phosphate, arsenate, arsenite and fluoride were also effectively adsorbed on zirconium(lV)-loaded
sorbeni .
