CdS-Bentonite Sulfide Ion Sensor: pH Effect and Selectivity

Autor: Kemawadee Udomphan, Ladda Meesuk, Atchana Wongchaisuwat

Publikováno v: Advanced Materials Research. 936:136-139

Bentonite is a commercial name of a clay mineral which consists of montmorillonite as main composition. Montmorillonite is a layered silicate clay mineral in which an alumina octahedral arrangement situated between two tetrahedral of silica sheet. Su
