Cation Selectivity in Sodium-Calcium, Sodium-Magnesium, and Calcium-Magnesium Exchange on Wyoming Bentonite at 298 K

the effect of oxytetracycline on serum calcium, phosphorus and magnesium in cattle

نتایج این مطالعه نشان می دهد که مقدار کلسیم (یونیزه و تام)، منیزیم و فسفر به طور معنی داری تغییر پیدا کرد به جزء مقدار کلسیم تام و منیزیم در روش داخل عضلانی که تغییر معنی داری نداشته است. بر اساس نتایج این مطالعه می توان نتیجه گیری کرد که اکسی تتراساکلین بر روی مقادیر سرمی کلسیم و منیزیم تأثیر می گذارد باید مقدار این کاتیون ها در بیماران، در هنگامی که اکسی تتراسایکلین استفاده می شود مورد توجه ق...

Calcium-Magnesium Exchange Selectivity of Wyoming Montmorillonite in Chloride, Sulfate and Perchlorate Solutions

The need to consider CaCl and MgCl complexes in Ca-Mg exchange reactions on montmorillonite was evaluated by examining cation selectivity in various anion backgrounds. The Ca-Mg exchange isotherms on SVVy-1 Wyoming bentonite were determined in 0.0125 M SO4, 0.025, 0.050, and 0.100 M Cl and 0.03 M perchlorate background. Calculated selectivity values for the reaction Ca + MgX^ Mg + CaA" were Kv ...

Electrolyte Disorders: Derangements of Serum Sodium, Calcium, Magnesium, and Potassium

W balance is measured by changes in osmolality. Osmolality is the number of osmotically active particles (osmoles) per liter of solution. (Osmolarity is expressed per kilogram). Hypo-osmolality indicates an excess of water relative to osmoles; hyperosmolality indicates water deficiency. The serum osmolality [in milliosmols per liter (mosm/L)] can be calculated by the following formula: Serum os...
