Numerous methods for the determination of phosphates (H₂PO₄⁻, HPO₄²⁻, PO₄³⁻, PPi) are described in the literature. However, the design of optical probes which are able to recognize specifically monohydrogen phosphate (MHP) ions, i.e. HPO₄²⁻, has been rarely considered. We herein devised an incisive chemodosimeter (FLH) for detecting HPO₄²⁻ over other phosphates successfully.

基于荧光素的化学计量仪对磷酸一氢的敏锐光学识别

为磷酸盐的确定的许多方法（H ₂ PO ₄ ^-，HPO ₄ ^2-，PO ₄ ^3-，PPI）在文献中描述。但是，很少考虑能够识别磷酸单氢（MHP）离子即HPO ₄ ^2-的光学探针的设计。我们在此设计了一种精密的化学计量仪（FLH），用于成功检测HPO ₄ ^2-优于其他磷酸盐。
