Description

Technical Field

[0001] This utility model belongs to the technical field of water quality analyzers, specifically an anodic leaching water quality analyzer device. Background Technology

[0002] Anodic stripping voltammetry (ASV) is a highly sensitive electrochemical analysis technique widely used for the detection of heavy metals in water (such as lead, cadmium, and copper). However, existing commercial anodic stripping water quality analyzers generally lack integrated pretreatment components, requiring users to manually perform sample pretreatment, resulting in low detection efficiency, high error risk, and limiting the degree of automation and field applicability of the instrument.

[0003] Existing ASV instruments typically analyze raw water samples directly. However, natural water bodies or industrial wastewater often contain suspended particles, colloids, or microorganisms, which may clog electrode micropores or adsorb metal ions, leading to a decrease in deposition efficiency. Furthermore, organic matter such as humic acid and surfactants in the water sample can adsorb onto the electrode surface (such as mercury film or glassy carbon electrode), forming a contamination layer that inhibits the electrodeposition of metal ions. To address these issues, we have proposed an anodic leaching water quality analyzer. Utility Model Content

[0004] To address the problems mentioned in the background art, this utility model provides the following technical solution: an anolyte leaching water quality analyzer device, comprising a water quality analyzer body, wherein the water quality analyzer body is connected to a pretreatment component.

[0005] The pretreatment assembly includes a preliminary filtration chamber, which is connected to an acidification and neutralization chamber via a first delivery pipe. The acidification and neutralization chamber is connected to an ultraviolet digestion chamber via a second delivery pipe. The ultraviolet digestion chamber is connected to the water quality analyzer body via a third delivery pipe. Pumps are installed on the first, second, and third delivery pipes.

[0006] Preferably, the preliminary filtration chamber has a water inlet, a sedimentation tank is provided at the bottom of the preliminary filtration chamber, a timer is provided on the preliminary filtration chamber, a first conveying pipe is provided at the top of the preliminary filtration chamber, and a secondary filter screen is provided between the preliminary filtration chamber and the first conveying pipe. The sedimentation tank handles large particles, the secondary filter screen intercepts fine particles, dual protection electrodes are provided, and the timer controls the sedimentation time to avoid insufficient sedimentation in a short time or delayed detection due to excessive sedimentation.

[0007] Preferably, the acidification and neutralization chamber is equipped with a gantry frame, a motor is mounted on the gantry frame, and a stirrer is connected to the output end of the motor through the gantry frame and the acidification and neutralization chamber. A pipette is mounted on the gantry frame, and a drip port is opened at the top of the acidification and neutralization chamber, with the drip port corresponding to the position of the pipette. This replaces manual acid addition, eliminates volume errors, and the stirrer accelerates the reaction and shortens the acidification time.

[0008] Preferably, the ultraviolet digestion chamber is equipped with an ultraviolet lamp with a wavelength of 254 nm and a power of 15W or higher, which degrades organic matter online, avoids electrode contamination, eliminates the need for external digestion equipment, and improves portability.

[0009] Preferably, the water quality analyzer body is equipped with a working electrode, which can be enriched. It is emphasized that this device still retains the core ASV detection function, and the pretreatment is only an auxiliary optimization.

[0010] Preferably, the sedimentation tank is detachably connected to the preliminary filtration chamber, which solves the problems of easy clogging and difficult maintenance of traditional filtration devices.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] During operation, the water sample enters the preliminary filtration chamber through the inlet. Large particles of impurities are separated by gravity sedimentation in the settling tank. The upper liquid is then finely filtered through a secondary filter. A timer controls the sedimentation time to ensure optimal filtration. After filtration, the sample enters the acidification and neutralization chamber through the first delivery tube. Nitric acid solution is precisely added using a pipette, and a motor-driven stirrer mixes the sample, adjusting the pH to the range of 1-2 to keep metal ions in a free state. The acidified sample then enters the ultraviolet digestion chamber through the second delivery tube. A 254nm ultraviolet lamp irradiates the sample, decomposing organic interferences and eliminating the risk of organic matter contamination on the electrode surface. After pretreatment, the sample enters the water quality analyzer body through the third delivery tube. A negative potential is applied to the working electrode, reducing metal ions to elemental metals and depositing them on the electrode surface, completing enrichment. This achieves fully automated "sample in - result out" detection, with standardized pretreatment to avoid human error. Attached Figure Description
