C. Namasivayam et K. Kadirvelu, Carbonised coirpith as an adsorbent for the removal of toxic ions, dyes and pesticides from wastewaters, I J CHEM T, 5(5), 1998, pp. 334-336
Carbonized coirpith was effective in the removal of toxic metal ions such a
s Hg(II), Pb(II), Cr(VI) and orthophosphate and dyes such as rhodamine-B, a
cid violet, procion orange and congo red and paraquat in aqueous phase syst
ems. Quantitative removal of dye and toxic metal ions and around 75% remova
l of phosphate and paraquat were observed.
