Claim 8:
9. The method of claim 1, wherein the adsorption inhibitor has a structure of X1—C(═O)—X2 or X1—C(═S)—X2, wherein X1 and X2 are each independently hydrogen, an alkyl group having 1 to 10 carbons, an alkenyl group having 2 to 10 carbons, an alkynyl group having 2 to 10 carbons, an aryl group having 6 to 15 carbons, a cycloalkyl group having 3 to 12 carbons, a cycloalkenyl group having 3 to 12 carbons, —OR1, —NR1R1′, or —SR1, provided that at least one of X1 and X2 is not hydrogen, and optionally X1 and X2 together form a ring, and
R1 and R1′ are each independently hydrogen, an alkyl group having 1 to 5 carbons, an alkenyl group having 2 to 5 carbons, an alkynyl group having 2 to 5 carbons, an aryl group having 6 to 10 carbons, a cycloalkyl group having 3 to 7 carbons, or a cycloalkenyl group having 3 to 7 carbons.
