Abstract

We have studied effect of water treatment sludge (WTS) on trace metals of sorghum hybrid (Sorghum bicolor (L.) Moench). In the present report it was for cadmium (Cd) content on background correction (BGC) mode with an atomic absorption spectrophotometer. The four treatments were Control, Compost, Alum + nitrogen, phosphorus, potassium (NPK), Compost + NPK. In the analysis, burner height of the atomic absorption spectrophotometer was adjusted to three levels; 3 mm, 6 mm, 9 mm. As a conclusion, 3 mm and 6 mm burner height conditions were better than 9 mm height for Cd analysis. And the conditions for widening the range, the mean, and the standard deviation (SD) values of observed absorbances as well as the condition for lessening the mean of observed background values are necessary for getting the better measuring of Cd. At the present experiment, 6 mm burner height condition is the best among the three burner heights.

수수 (Sorghum bicolor (L.) Moench)의 미량 광물 (微量鑛物) 성분의 한가지인 카드뮴을 원자흡광분광 분석기 (이하 분광기)를 이용하여 바탕선을 수정하는 방법 (BGC)으로 분석했다. 실험은 가) 비료 무시 용구인 대조구 (對照區), 나)정수장(淨水場) 슬러지를 부숙 (腐熟)시킨 구, 다) 정수장(淨水場) 슬러지에 질소, 인산, 칼륨 비료 (肥料)를 시용한 구, 라) 부숙 (腐熟)시킨 정수장 (淨水場) 슬러지에 질소, 인산, 칼륨 비료 (肥料)를 시용한 구의 네 가지였고, 처리조건 (處理條件)은 카드뮴을 분석할 때에 분광기의 버너의 높이를 3 mm, 6 mm, 9 mm로 조정하여 측정 조건으로 했는데, 흡광도 (吸光度)의 변화 범위 (變化範圍)와 흡광도의 표준편차 (標準偏差)가 크며, 바탕선의 크기가 작은 쪽이 카드뮴 측정 (測定)에 유리 (有利)한 것으로 나타났다. 본 실험 (本實驗) 결과(結果), 3 mm와 6 mm 버너 높이에서 9 mm 높이 보다 카드뮴 측정에 유효(有效)하며, 3 mm와 6 mm 중에서는 6 mm 버너 높이가 보다 적당한 것으로 나타났다.
