Problems solved by technology

[0003] The routine detection of heavy metal ions in petroleum wastewater requires pre-treatment of wastewater samples in the laboratory, and the operation is relatively complicated. Therefore, using microfluidic chip technology, a microfluidic chip and its use method are designed, which can detect heavy metal ions at one time According to the actual situation, combined with the treatment of wastewater samples, the full mixing of various reagent solutions is realized, and the structure of the cuvette is simulated, and the concentration of various heavy metal ions is detected by a spectrophotometer

Embodiment Construction

[0032] refer to Figure 1 to Figure 12 The shape and structure of the chip, a method for using a heavy metal ion detection chip in petroleum wastewater, consists of three parts: a sample liquid processing system, a solution mixing system, and a sample discharge system. It is characterized in that: the chip is in the form of a vertical cuboid, and the height is the long side. From top to bottom, there are sample liquid processing system, collection and storage system, solution mixing system, and sample discharge system. Chip supporting processing has main cover 18 and cuvette cover 15. The function of the cuvette cover 15 is to protect the special cuvette 1 from light. For example, the fluorescent nano-cluster reagent is used to detect heavy metal ions, and the reaction test solution needs to be protected from light. The main cover 18 is processed with friction beans that push the cover. Corresponding to the positions of the chip pool mouth microvalve 11 and each microvalve ...

Abstract

The invention provides an application method of a heavy metal ion detection chip in petroleum wastewater. The application method is characterized by including following steps: chip preparation, reagent preparation, sample solution treatment, sample solution separation, hybrid reaction, clean and storage. The application method of the heavy metal ion detection chip in the petroleum wastewater has the advantages that sample solution is mixed more sufficiently, detection accuracy is improved, detection effect improvement can be benefited from a design of a sample solution treating tower, detection is enabled to be more conveniently, more quickly and more accurately, treating operations can be changed flexibly according to actual situations of samples, and the sample solution separation can beperformed more precisely.

Description

technical field [0001] The invention relates to a method for using a multi-channel detection chip, in particular to a method for using a microfluidic chip for detecting the concentration of heavy metal ions in petroleum wastewater, which has the functions of filtering and mixing sample liquid to be detected. technical background [0002] At present, social and environmental pollution is becoming more and more serious, and petroleum wastewater is one of the pollution sources in today's society. Petroleum wastewater contains a large amount of toxic and harmful substances such as oil substances and heavy metals, which will indirectly cause harm to human health, so the detection of heavy metals has been highly valued by researchers. Microfluidic chip technology continues to develop, and the technology for designing microfluidic chips to detect various heavy metal ions is becoming more and more mature. Using microfluidic chips to integrate various basic operating units such as s...
