Abstract

본 연구는 최근 흡착제로서 활용도가 높은 biochar의 경쟁 흡착특성을 조사하기 위한 연구로서 참깻대 biochar가 주입된 삼각플라스크에 중금속(Cd, Cu, Cr, Pb, Zn) 표준용액을 단일 및 복합으로 구분하여 농도별로 흡착실험을 한 후 Freundlich 및 Langmuir 등온흡착식에 적용하여 흡착능(K, a)를 조사하였다. 참깻대 biochar의 단일 중금속에 대한 흡착능 (K)은 Pb (11.83) ≫ Cd(9.68) > Cr (8.38) > Cu (6.04) > Zn (3.76) 순이었으며, 복합 중금속에 대한 흡착능 (K)은 Pb(2.88) > Cu (2.41) > Cr (1.77) > Zn (1.38) > Cd (1.19) 순이었다. 참깻대 biochar의 단일 중금속 용액에 대한 최대흡착능 (a)은 Pb (102 mg g-1) ≫ Cd (86) > Cr (65) > Cu (55) > Zn (34) 순으로 Freundlich와 동일한 경향으로 나타났으며, 납의 흡착능이 가장 높았고, 아연의 흡착능이 가장 낮았으며, 참깻대 biochar의 복합 중금속 용액에 대한 최대흡착능 (a)은 Pb (88 mg g-1) > Cu(40) > Cr (21) > Zn (7) > Cd (5) 순으로 Freundlich와 동일한 경향으로 나타났으며, 납의 흡착능이 가장 높았고, 아연의 흡착능이 가장 낮았다. 본 결과를 ametal (monometal adsorption)/ a*metal(multimetal adsorption)의 비율로 보았을 때 aCd/ a*Cd (17.20) > aZn/ a*Zn (4.85) > aCr/ a*Cr (3.01) >aPb/ a*Pb (1.16) > aCu/ a*Cu (1.38)순으로 카드뮴이 가장 높았으며, 구리가 가장 낮은 값을 보였다. 카드뮴의 경우는 납과 구리에 비해 경쟁흡착에 의한 영향을 많이 받는 것으로 판단된다. (In a single and multiple heavy metals (Cd, Cu, Cr, Pb, Zn) and the reference standard solution injected kkaetdae biochar the conical flask as a study to investigate the utilization of high biochar competitive adsorption properties as adsorbents of this study are separated last after concentration by an adsorption experiment was investigated (K, a) the adsorption capacity is applied to the Freundlich and Langmuir adsorption Isotherms. Indeed for a single heavy metal adsorption capacity of the biochar kkaetdae (K) is Pb (11.83) »Cd (9.68)> Cr (8.38)> Cu (6.04)> Zn (3.76) was pure, heavy metal adsorption capacity of the compound (K) is Pb (2.88)> Cu (2.41)> Cr (1.77)> Zn (1.38)> was Cd (1.19) respectively. Indeed Pb (102 mg g-1) »Cd (86)> Cr (65)> Cu (55)> in the same Freundlich tendency Zn (34) in the order of the maximum adsorption capacity (a) of a single heavy metal solution is kkaetdae biochar showed, the higher adsorption capacity of lead, the lower the adsorption capacity of the zinc and, indeed a maximum adsorption capacity (a) to the solution of heavy metal compound is kkaetdae biochar Pb (88 mg g-1)> Cu (40)> Cr (21 )> Zn (7)> ​​showed the same trend with Freundlich Cd (5) in this order, the higher adsorption capacity of lead, the low adsorption capacity of the zinc. The present results ametal (monometal adsorption) / when viewed as a percentage of a * metal (multimetal adsorption) aCd / a * Cd (17.20)> aZn / a * Zn (4.85)> aCr / a * Cr (3.01)> aPb / a * Pb (1.16)> aCu / a * Cu (1.38) and the order of the highest cadmium, copper showed the lowest value. Is expected to receive a lot of influence on the competitive adsorption of lead and copper than in the case of cadmium.)
