A highly selective electrode for Bromide ion based on aza pyrilium derivative as an excellentionophore is described.The sensor exhibits a good linear response with a slope of ( 60±1 ) mV per decadeover the concentration range of ( 1×10-3 – 9×10-6 M ) , and a detection limit of ( 3×10-6 M ) of Bromideions .The electrode response is independent of pH in the range of(4.0 –9.5).Selectivity coeffici...

Supported Liquid Membrane in Metal Ion Separation: An Overview

Using liquid membrane and, in particular, supported liquid membrane (SLM) is a novel method of separation in comparison to other methods such as adsorption, extraction and ion exchange. SLM is a combination of simultaneous extraction and disposal whose high efciency and capability is proven by many studies. So far, many researchers have utilized SLM in various scientifc...

Gas Permeation Modeling through a Multilayer Hollow Fiber Composite Membrane

In this study, a time-dependent 2D axisymmetric model of a multilayer hollow fiber composite membrane for gas separation is proposed. In spite of the common multilayer membranes, which a dense layer coated on a porous support layer and subjected into the feed stream, here, the porous support is exposed to the feed gas. In this regard, the governing equations of species transport are developed f...

Manganese (M-selective PVC membrane electrode based on N-(2- picolinamido ethyl)-Picolinamide as ionophore

In this research, a PVC membrane electrode for Manganese (II) ions based on N-(2-Picolinamidoethyl)Picolinamide as neutral carrier was prepared. The electrode exhibits a Nemstian responseover Mn(II) concentration range of (1.0 x10-5 t01.0 X 10-1M) with a slope of 29.3±0.5 mV perdecade of concentration with a working pH range of 4.0-9.0. It has a fast response time (
