主　　题：Environmental deoxyribonucleic acid Antibiotic resistance genes Biochar Adsorption thermodynamics 

摘      要：Environmental deoxyribonucleic acid(eDNA),which includes antibiotic resistance genes,is ubiquitous in the *** interactions between eDNA and biochar,a promising material widely used in soil amendment and water treatment,greatly affect the environmental behavior of *** few experimental evidences are available yet,especially on the information of thermodynamics and energy distribution to explains the interactions between biochar and *** study investigated the adsorption of herring sperm DNA(hsDNA)on pine sawdust biochar,with a specific emphasis on the adsorption thermodynamics and site energy *** adsorption of hsDNA on biochar was enhanced by an increase in the pyrolysis and adsorption *** higher surface area,strongerπ−πinteraction,and weaker electrostatic repulsion between hsDNA and biochars prepared at high pyrolysis temperatures facilitated the adsorption of *** thermodynamics indicated that the adsorption of hsDNA on biochar was spontaneous and ***,higher temperature was beneficial for the adsorption of hsDNA on biochar;this was well explained by the increase in E*and F(E*)with the adsorption *** results are useful for evaluating the migration and transformation of eDNA in the presence of biochar.
