There-fore, the separation of the RANH relied on the
cation exchange with the ZIC-HILIC columns (Fig.
Cation exchange capacity (CEC) of a soil is a measure of the soil's ability to exchange positively charged ions in the soil with the surrounding soil solution and to attract and retain cations, such as those within plant secondary compounds (Brightsmith et al, 2008).
Cation Exchange Capacity (CEC) can be defined as the total sum of exchangeable cations (both positively and negatively charged ions) that a soil can hold [1] at a particular time.
During in-depth analysis, maximal binding of Bovine serum albumin and Bovine carbonic anhydrase was seen at the lowest pH and NaCl levels tested, whereas complete recovery was attained at high pH and NaCl levels--indicating that the main interaction between these proteins and the resin involves the
cation exchange (electrostatic interaction) of the Nuvia cPrime Resin.
209% of the variance and has positive loadings in Na+, Alkalinity and K+, which is indicative of
cation exchange triggered by salt water intrusion to a great degree.
There was significant effect of the treatments on the increments of the contents of Cd (Figure 1D); however, there was higher leaching of this element in T4, due to the decrease in the values of
cation exchange capacity and clay percentage along the soil profile (Tables 1 and 2).
Cation exchange sites in SOM arise from the dissociation of weakly acidic functional groups, particularly carboxylic and phenolic groups (Thomas and Hargrove 1984).
Sodium status as the ratio of exchangeable sodium cations are determined by the total
cation exchange capacity, the term is used in this case, exchangeable sodium percentage (ESP) is.
141] in dry basis and a theoretical
cation exchange capacity (CEC) of 3.
1986; 1965), while, the
cation exchange capacity (CEC) was determined using the method of Inglethorpe et al.
The value of pH, texture and
cation exchange capacity are shown in Table 2.
Soil nitrate and phosphate were determined through spectrophotometric method, total organic carbon through the method of (14) while
cation exchange capacity was determined using titration method.
