Semiconducting Polymer Microparticles as Solid Ionophore with Abundant Complexing Sites for Long-Li

What is it about?

This study develops an understanding of the facile synthesis of conducting microparticles bearing many functional groups and their structures governing the potentiometric susceptibility toward interaction between Pb(II) ions and the microparticles for fabricating robust long-lived Pb(II)-sensor, signifying the potential suitability of such novel materials for inexpensive sensitive detection of Pb(II) ions.

Why is it important?

This is demonstrated by good performance characteristics obtained during application, such as low concentration detection limit, short response time, wide pH windows, long lifetime, and good selectivity. In particular, the new long-life Pb sensors based on a novel sensing membrane with many complexation sites and thus fast and stable response have been achieved by a simplified process.The process for producing the copolymer microparticles and fabricating Pb(II)-sensor can be easily scaled-up in
