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.

Method for treatment of waste water containing organic pollutants

Magnesium aluminosilicate, silicic acid of which is not absorbed through digestive tracts on administration, can be produced by reacting polymeric sodium silicate having a siloxane structure of a polymerization degree of 10.sup.2 to 10.sup.4 with sodium aluminate in an atomic ratio of Al to Si of 1 - 2 : 1 and then reacting the reaction mixture with a water soluble magnesium salt in an atomic ratio of Mg to Al of 0.5 - 1 : 1.
