Analysis of Non-Ionic Surfactant by Solid Phase Extraction-HPLC Conforming to Water Quality Standard

Introduction

A standard value of 0.02 mg/L or less was established for non- ionic surfactants (NIS) by enforcement of a ministerial ordinance concerning water quality standards (ordinance of the Ministry of Health, Labour and Welfare No. 101, May 30, 2003). Although a notice had specified solid phase extraction-absorptiometry as the analytical method, solid phase extraction-high performance liquid chromatography (HPLC) (2 of Attached Table 28) was added in a partial revision in FY 2012. This article introduces an example of analysis of NIS in tap water by using Shimadzu HPLC.
