“…For risk assessment of FWAs, quantitative analyses of individual FWAs are necessary to determine their various toxic effects. A number of methods for the determination of individual FWAs have been applied, including thin-layer chromatography (TLC), 6 capillary zone electrophoresis (CZE), 7 high-performance liquid chromatography (HPLC), [8][9][10] and liquid chromatography-mass spectrometry (LC-MS).…”

A simple method was developed for the analysis of seven stilbene-type fluorescent whitening agents (FWAs) in paper materials by ion-pair reversed-phase high-performance liquid chromatography with fluorescence detection. These stilbene-type FWAs included two disulfonate, two tetrasulfonate, and three hexasulfonate compounds. After optimization of chromatographic conditions, the FWAs were satisfactorily separated using a reversed-phase column (RP-18) with the following isocratic mobile phase: methanol-water (60:40) containing 17.5 mM TBABr and 10 mM citrate buffer (pH = 7.0). The calibration plot was linear in the range from 5 to 500 ng/mL for two disulfo-FWAs and from 1 to 500 ng/mL for the other five FWAs. Precision levels of the calibration curve as indicated by RSD of response factors were 1.2 and 8.1%. Limits of quantitation (LOQ) ranged from 1.2 to 11 ng/mL.

The technologies of recycling lower quality waste paper have been developed in recent years. As one of suppliers for deinking agent, we also has developed and functionalized the deinking agent to solve various problems. In this report, we describe the basic knowledge of deinking agent and other chemicals for pulp recycling, such as repulping promoter, fluorescence quencher, slime control agent, and pitch control agent.
