Cation Exchange Capacity (CEC) CEC, as reported by nearly all soil testing laboratories, is a calculated value that is an estimate of the soils ability to attract, retain, and exchange cation elements. It is reported in millequivalents per 100 grams of soil (meq/100g). In order for a plant to absorb nutrients, the nutrients must be dissolved.

When the pH of the water is less than 7 the ammonia is present as the ammonium ion. As pH increases above 7, more of the ammonia is present as ammonium hydroxide. The ammonium ion is readily removed by cation resin. Good removal capacity can be expected in waters low in hardness.
It was shown that copper, nickel, cobalt and an uranylion by phosphate cationexchange resin sorbs at the expense of an ionic exchange and partially at the expense of formation of coordination bonds with ionogenic group of cationexchange resin.
(4) It is lightweight, relatively pathogen free, may contain antifungal properties, and has a high water holding capacity. Pine Bark. Composted pine bark may be substituted, in part, for peat moss. (3) Bark particles have a relative high cation exchange capacity, while most particles have internal waterholding capacity. The large moisture ...

Calcined clays have a relatively high cation exchange as well as water holding capacity. This material is a very durable and useful amendment. These inorganic soil amendments are generally utilized to increase the number of large pores, decrease water holding capacity and improve drainage and aeration.
d. cation exchange capacity (cec) and base saturation 1. CeC a) Definition CeC is a measure of the ability of the soil to adsorb cations. Plants are primarily able to take up the ionic form of nutrients via their roots. many of these nutrients are taken up as cations (remember, these are positive ions). most soils have at least some ability to
Cation exchange chromatography is a form of ion exchange chromatography (IEX), which is used to separate molecules based on their net surface exchange chromatography, more specifically, uses a negatively charged ion exchange resin with an affinity for molecules having net positive surface charges.
Mar 30, 2014· Selection of ion exchange resin Depends upon 1. type of the ions to be separated – cations or anions 2. nature of the ions to be separated strong or weak 3. efficiency of the resin: measured by ion exchange capacity Ion exchange capacity is the total ion exchange capacity in terms of the exchangeable functional groups expressed as meq/g of ...
Heating of phosphate cationexchange resin in the Hform in water within 30 hours at temperature of boiling of water slightly reduced size of exchange capacity. Therefore, interaction of cationexchange resin in Na and Hforms with salt solutions of copper sulfate, nickel, cobalt, chloride sodium, calcium and nitrate of uranyl were examined.
He and fellow investigators found that the soils macaws choose to consume at the clay licks do not have higher levels of cationexchange capacity (ability to absorb toxins) than that of unused areas of the clay licks and thus the parrots could not be using the

Kooli and Jones (1998) used acidtreated saponite for the preparation of Al and Zrpillared acidactivated clays, which incorporated less Al and Zr than the parent saponite, in consequence of the reduced cation exchange capacity (CEC) of the matrix following acidactivation.
Dec 11, 2017· Purolite removed EDC from all ion exchange production in the Philadelphia, USA facility in 2002. We plan to remove EDC from cation and anion exchange resin production in our Zhejiang, China location by the end of 2018. Resins manufactured .
