Abstract

The invention discloses an online water heavy metal analyzer. The heavy metal analyzer comprises an industrial-grade integrated control unit, a detection unit, an automatic sampling unit, a water sample pretreatment unit and an external input/output unit. The online water heavy metal analyzer provided by the invention can utilize the industrial-grade integrated control unit for automatically controlling the detection unit, the automatic sampling unit, the water sample pretreatment unit and the external input/output unit through a communication interface. According to the online water heavy metal analyzer, the modularized idea is adopted, the number and the types of the units can be increased and reduced conveniently, meanwhile, components inside the units are independent and also can be increased and reduced. Due to the adoption of a low-cost standard network cabinet, the overall cost can be lowered and convenience can be brought for the data processing.

Description

technical field [0001] The invention relates to the field of water quality analysis, in particular to an online water quality heavy metal analyzer. [0002] Background technique [0003] The determination of heavy metal element ions in water is an important part of water quality analysis. At present, the technologies used in the monitoring of heavy metal pollution in the water environment mainly include electrochemical analysis, atomic absorption spectroscopy, inductively coupled plasma-atomic emission spectroscopy, and inductively coupled plasma -Mass spectrometer technology and biological monitoring methods. The existing photometric colorimetric detection method has high cost, low detection sensitivity and precision (ppm), complex reagent components, easy to produce secondary pollution, and is greatly interfered by other components, and the measurement elements of a single analyzer are limited. If you want to detect more Users with many elements can only buy multiple ana...
