Abstract
In order to study the effect of temperature on underground water solution erosion feldspar , the paper applied groundwater chemical simulation software phreeqc to simulate the water chemistry relation -ship between solubility and temperature under different CO 2 partial pressure at the two situations that cal-cium feldspar , potash feldspar , sodium feldspar exist in solution at the same time or respectively .The simulation results show that the three kinds of feldspar present in solution at the same time .The solubility of calcium feldspar , potassium feldspar is far less than that of individual existence .The solubility of sodi-um feldspar is far more than that of calcium feldspar and potash feldspar .The solubility of sodium feld-spar increases with the rise of temperature quickly;the solubility of three kinds of feldspar increases with the rise of temperature at the existence of three kinds of feldspar in solution respectively .At the respec-tive existence of three kinds of feldspar , the higher the tempreture of groundwater solution and content of CO2 , the stronger the erodent capacity of three kinds of feldspar;the rise of temperature can drop the e-rodent capacity of three kinds of feldspar to groundwater solution in the situation that the three kinds of feldspar is present in the solution and can still enhance the erodent capacity of sodium feldspar .关键词
