酸性降雨에 의한 畓土讓內 金屬物質의 浸出 및 吸着能에 關한 硏究(Ⅰ) = The Effect of Synthetic Acid Rain on Leaching and Adsorption of Heavy Metals in Soil ( I )

다국어 초록 (Multilingual Abstract)

Leaching characteristics and adsorption ability of Fe and Mn in the paddy soil were studied with synthetic acid rain.
1. Leaching quantity of Fe from the paddy soil by acid rain was 8 times as much as by neutral rain, and 6 times for Mn.
2. Leaching quantity was changed with heat treatment methods of sample soil (ignition or air drying), with kind of meta](Fe or Mn) and with acidity of soil (acid or netural).
3. The adsorption ability of Fe on the paddy soil was twice as much as, that of Mn.
4. Langmuir isotherm equation was c/q=20C+10 for Fe(air drying paddy soil) and c/q=160 C - 610 for Mn(ignation paddy soil).
5. Contineous column experiment showed that the adsorption ability of Mn was above 100, and for Fe, it was changed with kinds of sample soil and pouring methods.
