The low-grade rock phosphate of Jhabua, Madhya Pradesh (India), was investigated for its possible application in the removal of lead, copper, zinc and cobalt ions from aqueous solutions. Effects of contact time, amount of adsorbent and initial concentration of metal ions were studied. Adsorption of heavy metal ions was found to follow the order: Pb2+ > Cu2+ > Zn2+ > Co2+. The probable mechanism of metal ions removal by rock phosphate was found to be by its dissolutions followed by subsequent precipitation.
对印度中央邦贾布瓦的低品位磷矿石进行了研究，考察其在从水溶液中去除铅、铜、锌和钴离子方面的潜在应用。研究了接触时间、吸附剂用量和金属离子初始浓度的影响。发现重金属离子的吸附顺序为：Pb2+ > Cu2+ > Zn2+ > Co2+。发现磷矿石去除金属离子的可能机制是通过其溶解，随后进行沉淀。
