The present invention relates to a method for producing a high specific surface area silicate titanate-based adsorbent, the object of which is to produce a silico titanate-based adsorbent in a large amount in an open state rather than a closed state at a low temperature and a short time To provide a way.n n n The present invention for achieving the above object is 0.5 to 2 times of tetraethyl orthosilicate, 3 to 6 times of NaOH, KOH, CsOH in molar ratio with respect to titanium isopropoxide in the manufacturing method of the adsorbent for liquid waste liquid treatment Prepare one selected from 130, 160 times H 2 O, mix these preparations in the above ratio, remove the water present in the upper, and aged at a temperature of 40 ~ 180 o C for 2 to 16 hours It is characterized by washing and drying. |
