Amine Contents, Thiol Contents, and Conversion Ratios for APTES, AHAMTES, and APDMES Treated DE^a

cross-linkerb	amine contentc (μmol/mg)	thiol contentd (μmol/mg)	conv ratioe (%)
APTES	1.10 ± 0.17	0.0312 ± 0.006	2.84
AHAMTES	0.15 ± 0.01	0.0181 ± 0.003	12.1
APDMES	0.11 ± 0.03	0.0130 ± 0.001	11.8

^aAll data are reported as mean ± standard deviation for n = 3 data points unless otherwise noted. APTES thiol content was determined using n = 9 data points.

^bType of aminosilane used to functionalize the surface of diatomaceous earth particles.

^cPrimary amine content of diatomaceous earth particles after silylation.

^dSulfhydryl content of silylated diatomaceous earth after NAP addition.

^eRatio between sulfhydryl content after NAP addition and amine content before NAP addition.
