อิทธิพลของปริมาณดินเหนียวต่อการดูดซับโลหะหนัก

Abstract

This paper presents results of studies about the effect of clay content to absorb heavy metals. By testing the ability of absorption of copper in soil solution. Soil samples showed that the soil sample consisted of seven series, testing by batch adsorption. The study found that 48 hour period of concentration of copper to be absorbed by the soil into equilibrium. The adsorption copper soil seven series from most to least were ground Mukdahan soil, Nongbua Lamphu soil, Udon Thani soil, Nakhon Phanom soil, Loei soil, Khon Kaen soil and Nong Khai soil, respectively, using the isotherm adsorption of Langmuir. The clay was mixed into the Khon Kaen soil. Adsorption of copper was increased. The total amount of clay ratio of 60 percent by weight of total clay ratio is most appropriate.
