合成ＰｂＳ和ＺｎＳ对Ａｇ２＋、Ｃｕ２＋、Ｃｄ２＋、Ｆｅ２＋、Ｍｎ２＋、Ｍｇ２＋、Ｓｂ２＋和Ｂｉ３＋等离子吸附量与温度关系的实验研究表明，其遵从Ｋｅｌｖｉｎ公式：在Ａ类吸附，即抗衡离子交换型吸附中，温度上升，其吸附量升降由反应热决定，本实验中Ａ类吸附多为上升型；而大部分Ｂ和Ｃ类吸附，即朗谬尔型及反朗谬尔型的吸附量则随温度上升呈指数下降。例外的仅有ＰｂＳ对Ｂｉ３＋离子的吸附，其吸附量随温度上升有微弱的上升。这可能与Ｂｉ３＋离子和吸附剂ＰｂＳ之间共晶反应和铅的铋硫盐的形成有关。Ａ类吸附的吸附量受介质条件变化影响很少。但对Ｂ和Ｃ类吸附，吸附量受ｐＨ和离子强度变化影响取决于三个因素：①吸附剂ＰｂＳ、ＺｎＳ表面电荷特性；②溶液介质条件变化时吸附离子在溶液中离子态的分布与变化；③被吸附离子在吸附剂中扩散和形成化合物或共晶的能力。因此，当ｐＨ增加时，Ｐｂｓ和ＺｎＳ对金属离子吸附量的变化表现出多样性：增加的有ＰｂＳ对Ｆｅ２＋离子的吸附；下降的有ＰｂＳ对Ｓｂ３＋离子的吸附和ＺｎＳ对Ｆｅ２＋、Ｍｎ２＋离子的吸附；不变的有ＰｂＳ对Ｂｉ３＋、Ｚｎ２＋离子的吸附和ＺｎＳ对Ｍｇ２＋离子的吸附。当溶液中离子强度增加时，由于溶液中自由态离子?
Experimental studies on the relationship between the amount of plasma adsorption of Ag2 +, Cu2 +, Cd2 +, Fe2 +, Mn2 +, Mg2 +, Sb2 + and Bi3 + by temperature and the temperature dependence of the synthesis of PbS and ZnS show that they conform to the Kelvin formula: In the A type adsorption, that is, the counter ion exchange type adsorption, In the experiment, most of the A-type sorptions are ascending type, while most of the B and C-type sorptions, that is, Langmuir-type and Langmuir-type sorption amount increase with temperature The index is down. The only exception to this is the adsorption of Bi3 + ions by PbS, with a slight increase in adsorption as the temperature increases. This may be related to the eutectic reaction between Bi3 + ions and the adsorbent PbS and the formation of lead bismuth thiosulfate. The adsorption capacity of A-type adsorption is less affected by the change of media conditions. However, for the adsorption of B and C, the amount of adsorption depends on three factors: the adsorption of PbS and ZnS on the surface of the adsorbent; the distribution and change of the ionic state of the adsorbed ions in solution when the solution medium conditions are changed ; ③ adsorbed ions in the adsorbent diffusion and the formation of compounds or eutectic ability. Therefore, when pH increases, the adsorption of Pb2 + and Pb2 + on Zn2 +, Zn2 + and Zn2 + on Zn2 +, Pb2 + ; There is PbS adsorption of Bi3 +, Zn2 + ions and ZnS adsorption of Mg2 + ions. When the ionic strength in solution increases, due to free ions in solution?
