## Abstract

The present invention relates to methods for processing liquid waste solutions containing organic molecules such as organic chemical molecules and biological agents or materials. More specifically, the invention relates to the use of solid phase binders for the removal of organic molecules from liquid waste solutions.

## Claims

### Claim 1

A method for removing organic molecules selected from the group consisting of organic chemical molecules and biological agents, from a liquid waste solution, said method comprising the steps of:
a) contacting said liquid waste solution with a solid phase binder comprising an adsorbent particle attached or entrapped in a matrix to form a solid phase binder:organic molecule complex, wherein the matrix is selected from the group consisting of glass, latex, agarose, nylon, polystyrene, polyacrylamide, polyacrolein, cellulose and copolymers thereof; and
b) separating said complex from said liquid waste solution to remove said organic molecules from said liquid waste stream.

### Claim 2 (depends on 1)

The method according to claim 1, wherein more than one organic molecule is present in the liquid waste solution.

### Claim 3 (depends on 1)

The method according to claim 1, wherein said solid phase binder comprises an adsorbent particle attached to a matrix.

### Claim 4 (depends on 1)

The method according to claim 1, wherein said solid phase binder comprises an adsorbent particle entrapped in a matrix.

### Claim 5 (depends on 1)

The method according to claim 1, wherein said adsorbent is selected from the group consisting of talc, glass wool, Fuller's earth, charcoal, activated charcoal, and glass beads.

### Claim 6 (depends on 1)

The method according to claim 1, wherein said organic molecule is MTBE.
