Immobilization of lead(II) ions from aqueous solutions on two natural coals and a sample of activated carbon (HS) was investigated. Batch adsorption experiments were performed (at 30 °C) to distinguish between immobilization mechanisms of natural coals and activated carbon. Experiments showed that composition of mineral matter can be essential for affecting the adsorption potential of natural coals to lead(II) ions. Magnesium and calcium were recognised as inorganic elements with evidently promoting role in lead(II) immobilization process.
