ESTD - 301 multi-parameter heavy metals water quality on-line analyzer

Introduction

The water quality of heavy metals in online analyzer using anodic stripping voltammetry, the detection method has been USA EPA and other authorities as standard detection methods.

Stripping voltammetry also called stripping polarography reverse, this method is to make the measured material, the measured ion potential polarographic analysis of limit current electrolysis under a certain time, then the change of the electrode potential, the concentration on the electrode material re dissolution, according to the process of stripping voltammetry get to the quantitative analysis.

Features:

Compared to spectrophotometry (colorimetric method), anodic stripping voltammetry (electrochemical) based on the heavy metal detector has many advantages:

1, can be done at the same time many parameters, such as an instrument for simultaneous detection of Pb + CD + cu;

2, low detection limit, the instrument is more suitable for surface water, groundwater, drinking water and industrial wastewater treatment by monitoring the application;

3, in the detection of lead, cadmium and mercury, arsenic and other parameters have obvious advantages.

Monitoring industry, mining, smelting, lead-acid batteries, leather and leather products, chemical raw materials and products of electroplating and surface treatment industry wastewater;

Pharmaceutical, power generation, nuclear power, petrochemical, papermaking, textile, chemical industry, municipal sewage and waste water monitoring;

Surface water, groundwater quality monitoring;

The water quality monitoring of the water plant, the municipal pipe network.
