The optimal pH, which was the major factor influencing the adsorption of cadmium, was around 6.0; and the higher concentration of cations such as K~+, Na~+, Ca~(2+), Mg~(2+), the lower the sorbing capacity of the microalgae; This effect, on the other hand, also illustrated that the ion-exchange was the main adsorption mechanism.

衣藻和固定化衣藻对重金属镉的吸附在pH6.0左右达到最佳吸附，但pH的变化对衣藻吸附镉的影响较大；固定化衣藻则在极低pH值下吸附受到显著影响，在pH3-8的范围内，所受影响不大；背景阳离子的存在对二者吸附的影响非常显著，这从另一方面证明了离子交换为衣藻生物吸附的主要机制。
