摘要：

The retention of ethoxylated nonylhylphenyl surfactants was determined in reversed-phase high-performance liquid chromatography (RP-HPLC) using various supports (C1, C2, C6, C8, C18, polyethylene-coated silica, and polyethylene-coated alumina). The retention data matrix was evaluated both by principal component analysis and cluster analysis. The retention characteristics of both polyethylene-coated supports were similar to that of C1, the retention capacity of RP columns for surfactants increased with the increasing length of the covalently bonded hydrocarbon chain. The retention of ethoxylated surfactants depended nonlinearly on the length of ehtyleneoxide chain suggesting that the polar ethyleneoxide chains are in folded state under the chromatographic separation.
