acute toxicity of alkali and alkaline earth metals on rohu, labeo rohita (hamilton) egg and hatchlings
the acute toxicity of salts of alkali and alkaline earth metals, such as sodium (na), potassium (k), calcium (ca) and magnesium (mg) were studied on the egg and larval stages of indian major carp labeo rohita (hamilton). the acute toxicity experiments were conducted followed by the range finding bioassay tests. the experiments were conducted in triplicates. the cumulative percentage of dead or ...
متن کاملThe effect of alkaline earth metals (Magnesium and Calcium) on Hydrogen storage efficiency of alanate nanopowders
Different Aluminum: alkaline earth metal atomic weight ratios effects on structure transformations in alanates nanopowders were studied. Changes in crystal structures from alane to alanates by increasing alkaline earth metals dopants in the mixture with slight changes in crystal structures from rhombohedral centered – trigonal (alane) to trigonal (magnesium alanate), and monoclinic (calcium ala...

متن کاملCatalyst-Free Conversion of Alkali Cellulose to Fine Carboxymethyl Cellulose at Mild Conditions
Cellulose fibers were converted into a valuable cellulose derivative, which is easily marketable with additional values. Alkali cellulose and carboxymethyl cellulose (CMC) is the most important cellulose derivatives. Alpha-cellulose was furnished as raw material for production of CMC, which is obtained from short cotton fibers, then purified. Alpha-cellulose is available in the international ma...
متن کاملEffects of Alkali and Alkaline Earth Metals on N-Containing Species Release during Rice Straw Pyrolysis
Abstract: To study the effects of inherent and external alkali and alkaline earth metallic species (AAEMs, i.e., K, Ca and Mg) on the behavior of N-containing species release during rice straw (RS) pyrolysis, different pretreatments were applied in numerous experiments. Results indicate that ammonia (NH3) and hydrogen cyanide (HCN) are the major N-containing species and that the yields of isocy...
