Example Embodiment

[0026] Reference Figure 1 to Figure 12 The shape and structure of a petroleum wastewater heavy metal ion multi-channel detection chip consists of three parts: a sample liquid processing system, a solution mixing system, and a layout system. It is characterized in that the chip is a vertical cuboid, and the height is the longest side of the cuboid. From top to bottom, there are sample liquid processing system, collection and storage system, solution mixing system, and layout system. The chip is matched with a main cover 18 and a cuvette cover 15. The main cover 18 is processed with friction beans that push the cover. At the positions of the main cover 18 corresponding to the chip pool opening microvalve 11 and each microvalve 3, the middle opening 19 of the pool opening microvalve 11 and the respective lid openings 17 are processed for convenient use. The cuvette cover 15 is processed with air holes 16 for facilitating liquid flow.

Abstract

The invention provides a petroleum waste water heavy metal ions multichannel detection chip. The petroleum waste water heavy metal ions multichannel detection chip is composed of a liquid sample processing system, a solution mixed system, and a blank layout system. The multichannel detection chip is characterized in that the chip prevents a vertical cuboid, and the height is the long edge. The multichannel detection chip comprises a liquid sample processing system, a collection storage system, a solution mixed system, and a blank layout system in order from up to down. and the chip is matchedwith a main lid and a cuvette lid. The petroleum waste water heavy metal ions multichannel detection chip is characterized in that a micro fluidic chip uses a stirring wheel for fully mixing a solution with manual control, the mixed system combined with a S-shaped mixing channel, so that the solution can be fully mixed, the detection accuracy degree is increased, the design of a liquid sample processing tower is in favor of increasing the detection effect, the detection is more convenient, fast, and accurate, a whole detection system has micromation, and is suitable for fields of scientific research and environment monitoring.

Description

technical field [0001] The invention relates to a multi-channel detection chip, in particular to a microfluidic control chip which has the functions of filtering and mixing sample liquid to be detected and detects the concentration of heavy metal ions in petroleum wastewater. 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 sample pretreatment, biological an...
