The main purpose of this work is to carry out adsorption study of different particle sizes of Activated Maiganga Coal. Activated carbon was produced from five different particle sizes of 63 μm, 300 μm, 425 μm, 600 μm and 2.0 mm from coal using potassium hydroxide as an activating agent. Freundlich and Langmuir adsorption kinetics as well as some quality parameters were studied for the produced activated carbon. These quality parameters were evaluated for the five different samples. With the gradual increase in PH values from 5.7 to 8.3, a corresponding decrease in uptake has been observed as a result of deprotonation of the adsorbent surface. The ash content was found to increases as the particle sizes increases. The n values which reflects the intensity of adsorption decreased from 0.573 to 0.061. The K values (Freundlich constant) present the opposite trend which increased from 69.984 to 163.682. The magnitude of Qo which indicates the amount of phosphate per unit weight of the adsorbent to form a complete monolayer on the surface also increased from 0.05 to 0.50. This work shows that, the finer the particle size of activated carbon, the greater the adsorption capabilities.Keywords: Activated Carbon, adsorption, Coal, Freundlich, Langmuir, Maiganga,
