One of the major problems in the analysis of ammonia (NH 3) using spectrophotometric method is highly coloured water sample. A reflectometric NH 3 sensor based on a facile single-step immobilisation of cobalt(II) (Co 2+) ion onto high capacity Dowex HCR-W2 microspheres has been developed to enable t...
