Theoretical Working capacity = 57 g/l x x x = If we now apply rinse correction for coflow ion.
Cation Exchange CapacityCation exchange capacity (CEC) is the amount of a ion that can be exchanged by another ion on the surface of a clay mineral. It is expressed in cmol(+)/kg, which is numerically equivalent to meq/100 g, where mol(+) represents moles of electrical charge. Theoretically, it can be obtained from the amount of isomorphous substitution, as shown by the structural formulae of the unit cells in ...
Evaluation of LogDerived Cation Exchange Capacity for ...Calculating Cation exchange capacity from well logs has showed promising results that agree with continuous Cation exchange capacity log derived values. The detection and estimation of water saturation in a hydrocarbon zone that has areas of shale formation can be estimated using CES models and V shale (V sh) models. However, V sh assume that the shale effect is only relative to the shale ...
Cation Exchange Capacity (CEC)Cation exchange capacity (CEC) is defined as the sum total of the exchangeable ions that a soil can adsorb. Exchangeable ions are positively charged ions (, Na+, Ca2+, K+) held on or near the negatively charged surfaces of soil particles and which may be replaced by other positively charged ions in the soil solution.

One mole is the atomic mass or molecular weight per liter of each ion or anion. Use the periodic table on the front cover of the text to find the mass of each element. Sum the masses of the constituent elements in each molecule.
How to calculate the ion exchange resin capacity? · If I have a ion exchange membrane and need to remove 2 g/L of sodium, how much resin would I need. I used the amount of substance of ce{Na} to calculate the amount of substance of ce{SO3H} needed for complete sodium removal. But this will not give me the correct mass since the resin is a polymer with that functional group attached ...
ASTMD7503 | Standard Test Method for Measuring the ... This test method describes the procedures for measuring the soluble and bound ions as well as the ion exchange capacity (CEC) of finegrained inorganic soils. Clay minerals in finegrained soils carry a negative surface charge that is balanced by bound ions near the mineral surface. These bound ions can be exchanged by other ions in the pore water, which are referred to as ...
