Carbon adsorbents are widely applicable to eliminate the water and air pollutions. In this study, a sanitary cotton was carbonized by heating at 300-900℃ under oxygen-free condition, is examined as a new inexpensive adsorbent. Some kinds of carbonized cotton prepared at different temperatures were contacted with ammonia and heavy metal solutions. The degree of their elimination was measured by using photo spectrometry or atomic absorption method. The results of experiments showed that the carbonized cotton prepared at 900℃ after treated with nitric acid remarkably eliminated dissolved ions in solution.
