摘要

A purine base adsorption material contains a 2:1 type layered clay mineral of [(E1m+a/mE2+b)(M1cM2d)(Si4-eAle)O10(OHfF2-f)] and/or its derivative, wherein m is a natural number of 2 to 4; parameters a, b, c, d, e, f satisfy inequalities: 0.2≤a+b0.75, a≠0, 0≤b, 0≤c≤3, 0≤d≤2, 2≤c+d≤3, 0≤e4, and 0≤f≤2; E1 is an element of Mg, Al, Si, Sc, Ca, Cr, Sr, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Ga, Zr or Ba, and turning into a polyvalent cation between layers; E2 is an element of Na, Li or K, and turning into a monovalent cation between layers; M1 is an element of Mg, Fe, Mn, Ni, Zn or Li; M2 is an element of Al, Fe, Mn or Cr; and the M1 and M2 form an octahedral sheet.
