'vermiculite' Determination on Whole Soils by Cation Exchange Capacity Methods*
-The proposed method is a modification of one by Alexiades and Jackson (1965). Calcium exchange capacity (CaEC) and potassium exchange capacity (KEC) are determined, after removal of organic matter and free iron oxides, by saturating the exchange complex with centrifuge washings of pH 7 acetate solutions of Ca or K, respectively. Excess salt in solutions remaining in contact with the soil after...
متن کاملInteraction of aminotriazole with montmorillonite and Mg-vermiculite at pH
The interaction of aminotriazole (AMT) at pH 4 on Wyoming montmorillonite (mainly with Na ions) and Mg-vermiculite has been studied by X-ray diffraction and infrared spectroscopy. The AMT is adsorbed on montmorillonite in the cationic form by cation exchange. The amount of pesticide adsorbed was 71 mEq/100 g, which comprises *91% of the CEC of this sample (78.2 mEq/100 g). Saturation was reache...
متن کاملOsmotic Swelling Behavior of Bovine Cartilage
Introduction Cartilage is a complex tissue whose extracellular matrix mainly consists of charged proteoglycan (PG) assemblies imbedded in a fibrous collagen network. PGs attract water and repel each other due to their negative charges generating a high swelling pressure. Collagens are proteins that form the fibrillar meshwork providing cartilage with its tensile strength. Cartilage extracellula...
متن کاملPermeability changes associated with osmotic swelling of bacterial protoplasts.
Bacterial protoplasts, released from confinement within the rigid wall of whole cells, imbibe water, swell, and burst unless their suspending medium contains high concentrations of solutes which have difficulty crossing the osmotic barrier in the protoplast surface membrane (C. Weibull, Exptl. Cell Res. 9:139, 1955; P. Mitchell and J. Moyle, J. Gen. Microbiol. 20:434, 1959). Hence, protoplast p...
متن کاملPregnancy Outcome with Intrauterine Insemination in Patients with Unexplained Recurrent Abortion Whose Partners Have Abnormal Hypo-Osmotic Swelling Test
Background: Recurrent abortion is defined as three or more consecutive pregnancy losses. We aimed to determine the relationship between male sperm parameters and hypo-osmotic swelling score and recurrent abortion. We also studied whether washing of spermatozoa and intrauterine insemination in patients with recurrent miscarriage and low score hypo-osmotic swelling test in male partners could imp...
