    Polymerclay nanocomposites have exhibited superior strength and thermo oxidative properties as compared to pure polymers for use in air and space craft; however, there has often been difficulty completely dispersing the clay within the matrices of the polymer. In order to improve this process, the ion exchange capacity of lithium clay is first lowered using twentyfour hour heat ...

     · In part 1 of our discussion on ion exchange capacity (CEC), we defined CEC and its function in soil and soilless media. As we mentioned, CEC has a significant impact on fertilizer and pH management in clay soils. However, in soilless growing media, it has little impact on fertility and pH management. In this article, we will discuss why CEC is not very important when it comes to soilless ...

    clay minerals results in underestimation of hydrocarbon volume in hydrocarbon producing reservoirs (Waxman and Smits, 1968). To evaluate the excess conductivity due to clay minerals, information is required about the number of counterions on clay surfaces, expressed as the ion exchange capacity (CEC) (Clavier et al., 1984). It was shown that ...

    The ion exchange capacity (CEC) of a soil is a measure of the quantity of negatively charged sites on soil surfaces that can retain positively charged ions (ions) such as calcium (Ca 2+), magnesium (Mg), and potassium (K+), by electrostatic forces. Cations retained electrostatically are easily exchangeable with ions in the soil solution so a soil with a higher CEC has a greater ...

    Cation Exchange Capacity (CEC)

    The capacity of the soil to hold and exchange ions is determined by the amount of clay and/or humus that is present. These two colloidal (negatively charged) substances are essentially the ion warehouse or reservoir of the soil. Sandy soils with very little organic matter (OM) have a low CEC, but heavy clay soils with high levels of OM have a much greater capacity to hold ions.

    The capture capability of clay minerals to ionic matters is dependent on their ion exchange capacity (CEC) since the capture process mainly occurs by the adsorption or ion exchange. The CEC of clay minerals is defined as "the quantity of ions available for exchange at a given pH, expressed in meq/100g (equivalent to cmol(+)/kg)" [25].

    Cationexchange capacity

    Cationexchange capacity (CEC) is a measure of how many ions can be retained on soil particle surfaces. Negative charges on the surfaces of soil particles bind positivelycharged atoms or molecules (ions), but allow these to exchange with other positively charged particles in the surrounding soil water. This is one of the ways that solid materials in soil alter the chemistry of the soil.
