Abstract

A Ti—Al—Zr—O metal oxide having the formula Ti x Al y Zr z O n , wherein x is independently 2-10, y is independently 0.5-6, z is independently 2-10, and n is independently 2x+3y/2+2z. A method of separating a mycotoxin from a matrix using a Ti—Al—Zr—O metal oxide.

Claims (7)

1. A Ti—Al—Zr—O metal oxide having the formula Ti x Al y Zr z O n , wherein x is independently 3-10, y is independently 0.5-5, z is independently 3-10, and n is independently 2x+(3y/2)+2z.

2. The Ti—Al—Zr—O metal oxide of claim 1 , wherein x is 3-5.

3. The Ti—Al—Zr—O metal oxide of claim 1 , wherein y is 0.75-3.

4. The Ti—Al—Zr—O metal oxide of claim 1 , wherein y is 2-5.

5. The Ti—Al—Zr—O metal oxide of claim 1 , wherein z is 7-9.

6. The Ti—Al—Zr—O metal oxide of claim 1 , wherein z is 7.5-8.5.

7. The Ti—Al—Zr—O metal oxide of claim 1 , wherein the Ti—Al—Zr—O metal oxide has the chemical formula Ti 8 Al 2 Zr 8 O 35 , where x is 8, y is 2, z is 8, and, subsequently, n is 35.
