BIOSORPTION OF MN (II) IONS FROM AQUEOUS SOLUTION BY JERUSALEM ARTICHOKE (HELIANTHUS TUBEROSUS L.) STALKS

The purpose of this paper is to tested Jerusalem artichoke stalks as a cheap biosorbent for its ability to remove Mn (II) ions from aqueous solution. Batch experiments were carried out to evaluate the effects of pH, biosorbent particle size, dosage, initial metal concentration and contact time. The...
