《The effect of interaction between Bacillus subtilis DBM and soil minerals on Cu(Ⅱ) and Pb(Ⅱ) adsorption》
The metal-binding quantity per unit minerals was used as the adsorption capacity to assess the impact of DBM on the metal adsorption capacities of minerals.The metal adsorption capacities and desorption of DBM,minerals and their complexes are shown in Table 1.Compared with the DBM complexes,kaolinite and goethite showed a very low adsorption capacity toward Cu(II)and Pb(II).The Cu(II)and Pb(II)adsorption capacities of kaolinite were 1.94 and 4.73 mg/g and the adsorption capacities of goethite were 5.44 and12.05 mg/g.After combination of DBM with kaolinite,the Cu(II)and Pb(II)adsorption capacities were increased to 2.92and 7.84 mg/g.However,the adsorption capacities were smaller by 32.72%and 22.15%,respectively compared with the theoretical values.The adsorption capacities of the DBM-goethite complex for Cu(II)and Pb(II)were 5.77 and 12.87 mg/g and were decreased by 32.98%and 29.59%,respectively,compared with the theoretical values.
