Heavy metal passivation and geosmin inhibition agent in aquaculture process, and preparation method thereof

Abstract

The invention provides a heavy metal passivation and geosmin inhibition agent in an aquaculture process, and a preparation method thereof, and belongs to the technical field of aquaculture quality evaluation. The preparation method of the agent comprises the following steps: firstly, selecting apricot shells with wide sources as a raw material, raising the temperature from room temperature to a target temperature of 550 DEG C, then keeping the temperature for 2 h, collecting crude pyroligneous liquor at the temperature of 550 DEG C through a destructive distillation and condensation process, then standing the crude pyroligneous liquor for one month by utilizing the instability of part of components in the pyroligneous liquor and easy precipitation caused by oxidation or polymerization andthe like, and discarding lower-layer tar and other components to obtain refined pyroligneous liquor which is used as a heavy metal passivation and geosmin inhibition agent in the aquaculture process.The passivation efficiency on copper, zinc and lead in the aquaculture process is high, the passivation range is wide, and a good passivation effect on various heavy metals is achieved; and fishy smell substances can be removed, and the market application prospect is wide.

AI Technical Summary

Benefits of technology

This patented technology helps prevent harmful algal blooms caused from excessive nutrients entering waterways during culturing for seafood crops such as salmon or shrimp. It uses certain chemical compounds that reduce unwanted growth while also being effective against other types of pollutants like chlorophyll-a (Cuprous) which causes damage when exposed to sunlight). These technical effectings include improved harvesting efficiency without causing environmental concerns due to overexposure to these contaminating elements, reduced costs associated with producing this type of product, enhanced safety measures for workers working around them, and potential applications across different industries where it could be used effectively.

Problems solved by technology

Technological Problem: Current solutions for reducing unwanted levels of contaminant elements like chromium (Cr), copper(Cu) zinc sulfide (ZnS), manganese dioxide (MgO2), iron oxides (Fe3Os)) in crops grown on open waters may cause negative effects including reduced taste sensations due to their presence in these environments. Additionally, there exist concerns over potential adverse impact upon human health when ingesting seafood containing significant amounts of chlorophyll which could potentially affect animal reproduction and reproductivity.
