Abstract
An aqueous solution containing aluminum is mixed with an aqueous solution containing calcium and/or an aqueous solution containing magnesium and, if necessary, further with an aqueous solution containing iron and the pH of the resulting mixture is adjusted to cause insolubilization of the metallic elements present therein and consequently gives rise to a coprecipitation product. This coprecipitation product is dehydrated and dried and, as an adsorbent, brought into contact with waste water containing organic pollutants. The adsorbent adsorbs and removes said organic pollutants from said waste water.
