과일 및 한약재 폐기물을 이용하여 중금속 제거력을 조사하기 위하여 Cd. Pb용액에서 사과껍질. 모과, 밤내피(밤 친 껍질). 인삼, 키위껍질. 대추. 원두커피 가루의 입자별, 농도별, 온도별 흡착 정도를 조사한 결과는 다음과 같다. 입자의 크기가 작아질수록 사과껍질을 제외한 모든 폐기물에 있어서 중금속 흡착력은 증가되었고, 중금속별 제거량은 Cd는 인삼폐기물이 3.506∼4.659㎎/g, Pb은 밤 친 껍질이 9.189∼9.582㎎/g으로 다른 과일 및 한약재 폐기물보다 높았다. 농도별 중금속 흡착량은 중금속의 농도가 높을수록 증가하였는데 Cd은 인삼 폐기물이 1.929∼3.800㎎/g. Pb은 밤 친 껍질이 0.930∼9.3685㎎/g으로 다른 과일 및 한약재 폐기물보다 높았다. 온도별 중금속 흡착량은 온도가 높아질수록 증가하여 Cd은 인삼폐기물이 3.800∼5.091㎎/g Pb는 밤 친 껍질이 9.368∼9.613㎎/g으로 다른 과일 및 한약재 폐기물보다 증가하였다. 이상의 결과로부터 물에 함유된 중금속을 제거하는데 과일 및 한약재 폐기물을 이용할 수 있을 것으로 생각된다.
To investigate Cd and Pb removability by the waste materials of fruit and oriental herb`s (apple peel. fruit of Chinese quince, chestnut-endoderm, ginseng, kiwi peel. Jujube after boiling, powder after brew coffee) in the heavy metal solution, Cd and Pb removability of seven kinds of fruit and oriental herb`s waste was investigated in the various conditions particle size of fruit and oriental herb`s waste(20, 40, 70 mesh), concentration of heavy metal(25, 50, 100 ppm) and reaction temperature(20, 30, 50℃). The removabilities by the fruit and oriental herb`s waste solids were increased as the particle size decreased in except of apple peel powder, concentration of heavy metal increased, and reaction temperature increased, The Cd removal content at the condition of particle size, conentration and temperature by ginseng waste was highest that the range were 3.506 to 4.659㎎/g, 1, 929 to 3.800㎎/g, 3, 800 to 5.091㎎/g, respectively. The Pb removal content at the condition of particle size, conentration and temperature by chestnut-endoderm waste was highest that the range were 9.189 to 9, 582㎎/g, 0.930 to 9.3685㎎/g, 9, 368 to 9.613㎎/g, respectively. Of the seven kinds of fruit and oriental herb`s waste materials, Cd and Pb removability by ginseng waste after boiling, chestnut-endoderm waste was highest, respectively.
