以异烟肼和2-羟基-1-萘甲醛为原料，经缩合反应合成了一种新的比色传感器2-羟基萘甲醛异烟酰腙（HINH）。该配合物在乙腈/水（1：3）二元溶液中对铝离子显示出良好的比色单一选择性和高灵敏度。基于UV-vis变化，检测限为1.0 × 10− 8 M Al 3+。
A novel colorimetric sensor, 2-hydroxy naphthaldehyde isonicotinoyl hydrazone (HINH), was easily synthesized by the condensation of isoniazid and 2-hydroxy-1-naphthaldehyde. The as-prepared compound showed effective colorimetric single selectivity and high sensitivity for aluminum cation in CH3CN/H2O (1:3) binary solutions. The detection limit is 1.0 × 10−8M Al3+based on UV–vis changes.
