A separable sorption apparatus has a sorption device and a heating device. The sorption device is filled with multiple sorbent granules. The heating device is detachably mounted on the sorption device and has a heater. The sorption device is put in a room that needs dehumidifying or deodorizing. When the sorbent granules have become saturated, the heater of the heating device is mounted into the sorption device to dehumidify or deodorize the sorption device to allow the sorption device to be reused. Since the heating device is detachable, the heating device does not occupy internal space of the sorption device. Thus, the sorption device has ample internal space for receiving the sorbent granules. Consequently, the sorption device has improved sorption effect.
