摘要:

Embedded in soils or immersed in a soil/solution system solid state ion selective electrodes, the Selectrodes, were used in continuous measurements of the activities of hydrogen, chloride and copper (III) ions of the solution phase. The total copper (II) concentration of the solution phase was assayed by the standard addition technique. Cation exchange isotherms were directly obtained by means of two pH-Selectrodes, one of which being charged with the exchanger material. The potentialities of “in situ” use of Selectrodes in soil-plant relationship work are emphazised.
