Remote acquisition of lead in water using Anodic Stripping Voltammetry method

This article presents the remote acquisition of lead in water using the Anodic Stripping Voltammetry method, which is implemented in a CheapStat-based platform. The electrochemical sensor makes use of a three-electrode cell as working (Glassy Carbon), reference (silver / silver chloride) and counter (carbon). Moreover, this work considers that the location of the measurement site is located in a place of difficult access, where there is not Internet network available. Then, in order to access to the lead concentration from anywhere in word, an RF connection using Xbee modules is used to transmit the information to a Raspberry Pi 3 module with Internet connection.

I. Introduction

Contamination of lead in water is a serious problem for health. Rivers that flow through mining camps or mineral rich soils near communities are exposed to heavy metal contamination. There are 50 elements classified as heavy metals, 17 considered as very toxic. One of the most common heavy metals found in drinking water is lead, which is present by the combustion of boats and ships and by the removal of the earth produced by mining [1].
