The leaching rate of titanium decreases with deceasing temperature, initial acid-to-calcium molar ratio and particle size but increasing liquid-to-solid ratio. And the leaching rate of calcium increases with increasing temperature, initial acid-to-calcium molar ratio, liquid-to-solid ratio but ...

Rabbits with the body weight of(2. 0 ± 0. 5) kg were chosen,to study the effects of sustained-release calcium hydroxide and sustained-release hydrochloric acid on nutrient digestion and absorption of rabbits. The results showed that sustained-release calcium hydroxide promoted digestion and absorp...
Mix 1g of the sample with 20 ml of water, and add sufficient acetic acid to form solution. The calcium salt test (IT-10) is positive. Content analysis Accurately weigh about 1.5g of sample into a beaker and then gradually add 30ml of dilute hydrochloric acid (TS-117). After the sample...
