Carbonate co-precipitation, using sodium or calcium carbonate, can also be helpful, for instance, for soluble lead reduction; lead carbonate is essentially insoluble (0.00011 g/100 mL @20°C) and will precipitate out. Phosphate precipitation is also an option although this is not such a common process.
