5/7/2017, · In general, low pH (more ,acidic,) conditions favour adsorption more than higher pH (more basic) conditions [80, 82, 83]. In the case of NH 4 + adsorption however, the opposite is found to be true. As can be seen in Figure 3.4, at any given solution concentration an increase in the solution pH results in greater amounts of NH 4 + ,being, adsorbed [77].
