The results show that the initial ammonium concentration
had a significant influence on the ammonium uptake amount. With
the increase in initial ammonium concentration, the ammonium
adsorption capacity of the synthesized ceramic adsorbent increased
from 28.5 mg L1 at initial ammonium concentration of
4000 mg L1, reaching the maximum value of 75.5 mg g1 when
the initial ammonium concentration was 10,000 mg L
