Abstract

The invention provides an online measuring device and method. The online measuring device is used for detecting the ingredients of heavy metal in water and the content of the ingredients. The online measuring device comprises a sampling guide pipe, laser sources, a measuring window, a laser intensity detecting instrument, a signal processor and an electromagnetic valve. Online real-time measurement for the heavy metal in water is achieved, the technology is used for real-time online measuring for the water quality state in a water purifier, the replacing state of a filter element in the water purifier can be effectively reminded, and a traditional unscientific count-down-type filter-element replacing method is changed. The measuring range of the online measuring device is ppb, the error is small, real time monitoring for the content of the heavy metal in water can be achieved, no chemical reagent needs to be added, and the online measuring device is simple and convenient.

Description

Technical field [0001] The invention relates to an online measuring device, in particular to a measuring device and a measuring method for heavy metal components and concentrations in water samples. Background technique [0002] Due to the rapid development of industry in recent decades, it has put a lot of pressure on our environment, and has also led to varying degrees of heavy metals in drinking water exceeding the standard. Among them, heavy metals cannot be decomposed in water, and they are very harmful to the human body. In water, heavy metals may also combine with other harmful substances to form more toxic harmful substances. If drinking water containing heavy metals for a long time, it will cause irreversible damage to the human body. [0003] At present, for the measurement of heavy metals, the heavy metals in water are usually measured offline. One method is to use other simple methods in the laboratory as colorimetry. By adding chemical reagents, different concentra...
