DATA SET 21: ION-EXCHANGE INFORMATION

This data set is needed only if NOMZ > 0. (NOMZ, the number of ion-exchanged species, is specified in Data Set 17). This set reads information of ion exchange information for NSITE exchange sites. Three groups of data are needed.

  1. Ion-exchange sites: containing the following one variable:

NSITE = Number of ion-exchange sites.

  1. Ion-exchange species: The total number of lines in this subset is NSITE. Each line contains the following two variables for the I-th site for I = 1, NSITE:
  1. NOMZI(I) = Number of ion-exchanged species participating in reactions at the I-th exchanged site.
  2. LNI(I) = Indicator for the "reference" ion-exchange species for the I-th site. It gives the location of this "reference" species on the ion-exchanged species list.
  1. Ion-exchange capacity: The total number of records in this subset is NMAT, each may include multiple lines. Each record contains the following variables, for J = 1, NSITE, J = 1, NMAT,

CECM(J,I) = Ion-exchange capacity (equivalents per unit mass of solid) for the J-th site in material I.
