Exposure to high levels of heavy metals exerts serious health hazards humankind. It is, hence, imperative limit exposure by avoiding their consumption, direct or indirect, and appropriately disposing items that may contain metals. To explore removal efficacy, montmorillonite (MMT), a type clay, was prepared at varying dosages (0.5, 1.0, 1.5 wt%) fabricate polysulfone mixed matrix membranes for ...

tin(ii)-ion-selective electrode consisting of dibenzo-18-crown-6 (db18c6) as an ionophore inpvc matrix was developed. the influences of membrane composition, selectivity, response time,reversibility and temperature on the electrode performance were investigated. the electrodeshowed a near nernstian response for sn2+ ions over a concentration range from 1.0× 10-6 – 1.0× 10-2 m with a slope of 27...
