氧瓶燃烧(burning in oxygen flask)离子色谱法(ion chromatography)鱼(fish)非金属元素(non-metallic element)本实验先用氧瓶燃烧法将鱼样中氯,氮,硫元素转变为阴离子,再以水为吸收液,用离子色谱法同时测定溶液中各阴离子的含量.本法具有吸收完全,检测快速准确,干扰少等特点,适用于生物样品中多种无机元素的同时...
op. cit.Ignites in air above 261°, in oxygen below 260°, burning to the dioxide; combines readily with hydrogen; combines in the cold with fluorine, chlorine, and bromine; combines with carbon at high temperatures; reacts with silicon, phosphorus, arsenic, antimony and bismuth at their ...
1. The environmental protection index will include capital input in the areas of environmental protection, annual sulfur dioxide emission and chemical oxygen demand. 2. " Industrial discharges like carbon and sulfur dioxide are major contributors to air pollution, " the environmental specialist said. ...
For this mechanism, depletion of GSH results in an accumulation of reactive oxygen species via hydrogen peroxide-dependent processes (Miccadei et al., 1988). The oxygen radicals react with membrane phospholipids, forming lipid peroxides that alter membrane structure, causing it to break down. ...
Supplying a sulfur-containing carbonaceous fuel to a boiler furnace (12), supplying a calcium carbonate-containing absorbent having a predetermined d50 particle size to the furnace, supplying an oxygen-containing gas to the furnace, A st... ロッカ,アンティ 被引量: 0发表: 2019年 加载更多站...
Burning: Burning or combustion is an exothermic reaction in which a chemical compound reacts exothermically with oxygen. Exothermic reactions are reactions which release energy into the environment. Answer and Explanation:1 You cannot get sulfur dioxide from sulfur without burning. The only chemical re...

Noun1.sulfur dioxide- a colorless toxic gas (SO2) that occurs in the gases from volcanoes; used in many manufacturing processes and present in industrial emissions; causes acid rain sulphur dioxide dioxide- an oxide containing two atoms of oxygen in the molecule ...
Sulfur gas appears reddish, hydrogen is green and oxygen is blue.(硫磺气体呈红色;氢气呈绿色;氧气呈蓝色。) The emission of sulfur dioxide when high-sulfur coal is burned is restricted by law.(高硫煤燃烧过程中的二氧化硫的排放是受到法律限制的。) The others are carbon, oxygen, nitrogen, hydrog...
in the dS-34 values of co-genetic minerals. The differences between minerals can be used to estimate the temperature of equilibration. The dC-13 and dS-34 of co-existing carbonates and sulfides can be used to determine the pH and oxygen fugacity of the ore-bearing fluid during ore ...
