钾对铵离子在蛭石矿物表面吸附与层间固定的影响

Effect of potassium on surface adsorption and interlayer fixation of ammonium in vermiculite

    摘要
  • 摘要: 在K+、NH4+不同施用顺序的情况下研究了蛭石对NH4+的晶层固定 ,证实了K+的存在对NH4+的矿物晶层固定不具有影响。在Ca2+-NH4+二元系统和Ca2+-NH4+-K+三元系统中 ,对NH4+在蛭石表面的吸附进行了研究 ,结果同样显示 ,K+对NH4+在蛭石表面的吸附位点不具有竞争作用。

     

    Abstract: This paper, by analyzing ammonium adsorption at the surface of vermiculite in the binary system (Ca2+ and NH4+) and ternary system ( Ca2+, NH4+and K+), and ammonium fixation in the interlayer of vermiculite with addition of potassium, illustrated that potassium couldn't reduce the adsorption of ammonium at the surface of vermiculite and fixation in the interlayer.
