There are many sample preparation methods for heavy metal detection of soil samples, but each has its advantages and disadvantages.Based on the above two psithurisme pretreatment methods, the detection limit, precision, accuracy and actual soil sample measurement value of mercury detection in soil by atomic fluorescence were compared with atomic fl
The removal of Cd(II) onto granular activated carbon (GAC) and kaolinite in singlecomponent systems has been studied using batch adsorption.Batch adsorption studied werecarried out under various amount of GAC and Kaolinite, Cd(II) ion concentration, pH viqua-f4 andcontact time.The experimental data was analyzed by Langmuir, Freundlich and Redlich-P

Abstract Background Extensive loss of donor neural stem cell (NSCs) due to ischemic stress and low rate of differentiation at the site of cell graft are two of the major issues that hamper optimal outcome in NSCs transplantation studies.Given that histone deacetylases (HDACs) modulate various cellular processes by deacetylating histones and non-his
Aiming at the problem of traffic data distribution shift caused by new unknown attacks in the industrial Internet, a malicious traffic identification method based on neighborhood filtering and stable learning was proposed to enhance the effectiveness and robustness of the existing graph neural network model in identifying known malicious traffic.Fi
