摘要
采用高效液相色谱法 ,用 YWG C1 8( 30 0× 3)柱 ,对高吸水性树脂中残留丙烯酸含量进行了分析 ,得出了合适的测定条件。流动相 (体积比 )∶ ( 0 .0 1 mol/L的 p H=9.1 82硼砂缓冲溶液∶ H2 O)∶ CH3OH=( 1 0∶ 2 0 )∶ 70 ;流速 :1 .0 ml/min;检测波长 :2 1 0 nm。
An analysis method of residual acrylic acid in Super Water-absorbing resin by high performance liquid chromatography,using YWG C18(300×3) column,ultraviolet absorption detector(210nm),flow rate(1ml/min) and aqueous-sodium tetraborate solution of inorgqnic salt-methanol as mobile phase is described.The method can be used for controlling the quality of residual acrylic acid in super water-absorbing resin.
