Lithium Oxide Content in Alumine Determined by Atomic Absorption Spectral Analysis 原子吸收光谱法测定氧化铝中氧化锂含量
Δ~ 9-Tetrahydrocannabinol was first extracted from hemp seed oil with methanol-petroleum either, and then purified by a column of activated alumine, was determined by gas chromatography. 用甲醇石油醚提取大麻籽油中的Δ9四氢大麻酚,然后通过活性氧化铝柱层析净化,再对其进行气相色谱测定。
During seed maturity of faba bean, alumine was from high to low, then it increased, the lowest was only about 12%. 在蚕豆结实过程中清蛋白含量由高至低再升高,最低为20%左右,最终达68%;
The colloid ed alumina hydroxide was prepared by precipitation using PEG as dispersing agent. Then the colloid was calcined at 800~ 1100 ℃/ 2h to get the nano powder of alumine. 以不同聚合度的聚乙二醇(PEG)为分散剂,采用沉淀法制备氢氧化铝胶体,胶体经800~1100℃高温煅烧得到纳米氧化铝粉体。
Determination of the dissolvability of alumine in calcium aluminate for water clarifying agent 净水剂用铝酸钙粉中氧化铝溶出率的测定
