鐵礦石化學分析方法亞硝基- r鹽光度法測定鈷量Chemical industry information not merely embodyed the ordinary chemistry information substance, chemistry manufacture technological process and representative installation introduction are still have, in case contacing legal institutions sulphuric acid ? nitric acid industry system law ( ammonia oxidate law ), synthetic ammonia industry, chlorine and caustic soda are manufacture to electrolysis salt water, along with electrogilding, refine aluminium, iron - smelting and steel - smelting, cement and glass manufacture summarized account, the mineral oil is refined, hence, the chemical industry information education is contrastd against the ordinary chemistry information education, proper such representative means, be living, the means interpreted is in speech oridinarily wholly adoptd in the chemical industry information education, now most of tutors also is adopt the means interpreted in speech, cause that the chemical industry information education is insipid like this, student lack interest to chemical industry information study, but as a result of value the pair foundation, light practice, student may say the become a mere formality to chemical industry information study o since multi - med
化工知識不僅包含了一般化學知識的內容，還帶有化學生產工藝流程及典型設備的介紹，如接觸法制硫酸，硝酸的工業製法（氨氧化法） ，合成氨工業，電解食鹽水製造氯氣和燒堿，以及電鍍、煉鋁、煉鐵和煉鋼，水泥和玻璃的生產簡介，石油的煉制等，因此，化工知識教學與一般化學知識教學相比，應有其典型的方法。在過去，化工知識的教學一般都採用口頭講解的方法，現在大多數教師也是採用口頭講解的方法，這樣使得化工知識的教學乏味，學生對化工知識的學習缺乏興趣，又因重視雙基，輕實踐，學生對化工知識的學習可以說流於形式。由於多媒體的輔助教學的高效性、形象直觀性、新穎性和多樣性、人工模擬等特點，很適合化工知識的教學，應用多媒體教學化工知識可以解決目前存在的諸多問題，如：模型短缺、組織參觀活動困難、教育經費不足、學生不易觀察等。Inorganic salts, such as a1 ( no3 ) 3, zrocl2, ticl3, et al. was used as raw materials and corresponding hydroxides were deposited on the surface of graphite particle with heterogeneous nucleation process ; composite particles of graphite / oxides were obtained after heat treatment. in this paper, preparing conditions and properties of composite particles were studied
本論文以無機鹽（硝酸鋁、氧氯化鋯、三氯化鈦等）為原料，在石墨的稀懸浮液中應用非均勻成核技術，使水解產物（水合氧化物）沉積到微米級鱗片石墨表面，經洗滌、烘乾和熱處理制備出石墨氧化物復合粉體。Otherwise we found from the experiments that the chloride system erodes seriously the equipment, and that the powders from the sulfate system are too large in size. therefore, only the powders from the system containing alcohol, compared with the powders from the system without alcohol, are fleecier and can be collected more easily
水，乙醇，硝酸鎂和硝酸鋁適宜作為合成尖晶石的起始物，因為通過試驗發現氯化物系統對設備的腐蝕性較大；硫酸鹽系統得到的粉末較粗；含有乙醇的系統得到的粉末比沒有乙醇的系統得到的粉末蓬鬆，易收集。The sample was dissolved by nitric acid and tartaric acid, and determined by aas with lanthanide oxide and edta masking al for determination of ca, with hc1 precipitating pb for determination of sn and al
摘要通過先加酒石酸、硝酸溶解樣品，用氧化鑭、 edta聯合掩蔽鋁來測定鈣，鹽酸沉澱鉛后測錫、鋁的試驗，採用火焰原子吸收光譜法測定錫、鈣和鋁。分享友人
