通过衍生反应,建立了用共振散射光谱法测定4-壬基酚的方法.在碳酸钠介质中,痕量4-壬基酚与丹酰氯反应,产物在300～600 nm波长范围有很强的共振散射光.在选定的测定波长396.8 nm处,共振光散射强度的改变值与4-壬基酚质量浓度在6.20×10~(-4)～6.00×10~(-2)mg·L~(-1)范围内呈线性关系.方法检出限为0.20μg·L~(-1).结合C_(18)柱固相萃取分离,应用于环境水样和合成水样中4-壬基酚的测定,样品加标回收率为91.25%～94.50%,相对标准偏差小于4.0%.

4-Nonyphenol was determined by resonance scattering spectrometry as its derivatization product with DNS-Cl. The derivatization reaction was carrried out in 0. 5 mol· L^-1 Na2CO3 solution, and resonance scattering spectrum of the reaction product was observed in the wavelength range of 300-600 nm, with its peak at 396. 8 nm. Linear relationship between the values of increase in intensity of resonance scattering （△I） and concentration of 4-nonylphenol was obtained in the range of 6.20× 10^-4-6.00×10^-2mg· L^-1 , with its detection limit of...
