实验研究表明，随着溶液pH值的升高，石英对Cu2+、Pb2+和Cd2+等重金属离子的吸附量和表面吸附覆盖率逐渐增大，而表面反应产物的结合形态相应地出现由单核化合物、多核化合物[SOCu4(OH)4+3]，直至表面沉淀[SOH…Cu（OH）2(S)]。随着温度升高，石英对Cu2+、Pb2+和Cd2+等重金属离子的吸附量逐渐减小。而随着溶液离子强度的增大，石英对Cu2+离子的吸附量和表面离子覆盖率也逐渐减小。可见，溶液pH值等介质条件对石英表面反应具有很大的影响，甚至可导致金属离子与石英表面反应机理与模式的改变，即由吸附反应向表面沉淀变化。
Experimental results show that with the increase of solution pH, the adsorption capacity of quartz on Cu2 +, Pb2 +, Cd2 + and other heavy metal ions and the surface adsorption coverage gradually increase, while the binding form of the surface reaction products correspondingly appears from mononuclear compounds, Polynuclear compound [SOCu4 (OH) 4 + 3] until the surface precipitated [SOH ... Cu (OH) 2 (S)]. With the increase of temperature, the adsorption capacity of quartz on Cu2 +, Pb2 + and Cd2 + and other heavy metal ions gradually decreased. With the increase of solution ionic strength, the adsorption capacity of Cu2 + and the surface ion coverage of quartz decreased gradually. It can be seen that the medium conditions such as solution pH have a great influence on the quartz surface reaction and even lead to the change of the reaction mechanism and mode of the metal ions and the quartz surface, that is, the change from the adsorption reaction to the surface.
