초록
마이크로파 시료 분해법이 식물체와 퇴비 중의 K, Ca, Mg, Cu, Zn, Mn등을 분석하는데 적합한가를 검정하기 위하여 기존의 습식분해법과 비교하였다. 분석시간은 기존의 습식분해법이 4~6시간 걸리던 것에 비하여 마이크로파 분해법에서는 1시간 이하로 단축할 수 있었으며, 두 분석법간의 각 성분별 분석값의 상관계수(
To verify the suitability of microwave digestion method for analyzing macro nutrients and metals. K, Ca, Mg, Cu, Zn, and Mn contents in plant and composts were investigated comparing with conventional wet digestion method. Because it takes short time to digest metal samples by using microwave method compared with conventional wet digestion method. Digestion time for metal samples was four to six hours long for wet digestion, while one hour long for microwave digestion. Determinant coefficients of Cu, Mn, Zn, Ca, K, and Mg contents between two analyzing methods were 0.99, 0.99, 0.94. 0.97, 0.98, and 0.91, respectively. In the case of Ca and K, microwave digestion method analyzed their contents relatively low compared with wet digestion method. Meanwhile, microwave digestion method analyzed the contents for Cu, Ma, and Zn relatively high compared with wet digestion method. This study results in that microwave digestion method could be an alternative to replacing conventional wet digestion method.
