| 摘 要： | 空气──乙炔火焰原子吸收测土壤全钙，由于干扰因子多，准确度欠佳。土壤经硝酸──氢氟酸──高氯酸消煮后，加入氯化 和三乙醇胺，空气─乙炔火焰原子吸收法测定，准确度有较大提高，优于加氯化 、氯化 和氯化钠两种方法。 |
| 关 键 词： | 原子吸收法，空气──乙炔火焰，土壤全钙，三乙醇胺，土壤化学分析（34BA49BC），农业化学研究法（49BG），土壤矿物（37HA49BC）。 |

| Abstract: | When using air-acetylene flamde atomic spectrometry(AAFAS) to analyze the total calcium in soil,the accuracy is not good, because of having many interference factors Boiling the soil in HAO_3-Hf-HClO_4,then added LaCl3 and(HOCH_2CH_2)_3N and analyze the total Caloium in soll with AAFAS.This method greatly improved the accuracy and are superior to another two methods with adding LaCl_3 and LaCl_3+NaCl. |
