Abstract:
... Bentonite was used as adsorbent, which was modified by aluminum cross-linking and tannin double modification (Al-Tan-Bent), and the adsorbent has excellent removal performance for ammonia nitrogen (NH₄⁺-N) from low temperature wastewater. In the experiments, the effects of adsorbent dosage, pH, contact time, and coexisting ions were analyzed in detail. The kinetic models were fitted by experimenta ...
