The pyrogallol red (PR)-based Cu complex was proven to be an effective and selective colorimetric chemosensing ensemble for recognition of oxalate over other anions in a perfect aqueous solution. The addition of oxalate to the PR-Cu complex resulted in a colour change from purple to orange colour due to the regeneration of PR by the chelation of oxalate with Cu , while other anions did not induce any significant colour change. Moreover, it was revealed that no obvious interference was observed during the titrations with oxalate into each other anion. Therefore, the PR-Cu complex can be used as a simple and practical colorimetric chemosensor for detecting oxalate.
基于连苯三酚红（PR）的铜配合物被证明是一种有效且具有选择性的比色化学传感体系，可在理想的水溶液中识别草酸盐，而不是其他阴离子。向PR-铜配合物中加入草酸盐会导致颜色从紫色变为橙色，这是由于草酸盐与铜螯合使PR再生，而其他阴离子不会引起任何明显的颜色变化。此外，结果表明在用草酸盐滴定其他阴离子的过程中未观察到明显干扰。因此，PR-铜配合物可作为一种简单实用的比色化学传感器来检测草酸盐。
