摘要:

An experiment was conducted to evaluate extraction methods for the determination of nitrate in a synthesized pine bark substrate. It was found that prior to nitrate determination, oven dryino of the pine bark sample was necessary followed by rewetting and extraction in a vacuum for 72 hours. Using this technique, about 65% of applied nitrate was recovered.
