前言
习近平总书记2013年提出了“一带一路”（The Belt and Road，缩写B&R）倡议。“十三五”期间，中国石油和化工企业“走出去”步伐不断加速，市场份额进一步增大，在全球产业链、供应链、价值链中发挥了重要作用。然而，“走出去”企业尤其是石油化工企业的员工本土化培养培训迫切需要相关的教学资源。2021年10月中共中央办公厅、国务院办公厅印发《关于推动现代职业教育高质量发展的意见》，明确提出要通过提升中外合作办学水平、拓展中外合作交流平台、推动职业教育走出去等措施打造中国特色职业教育品牌，推出一批具有国际影响力的专业标准、课程标准、教学资源。基于此，为顺应“走出去”企业人才培养的需要和国家职业教育改革发展的要求，本教材编写组以新修订实施的《中华人民共和国职业教育法》为依据，以科学性、先进性、适用性为目标，突出职业教育类型特色，紧扣实际、力求实用，解构重构了《分析化学》内容，编写了《化学分析（中英对照版）》和《仪器分析（中英对照版）》。
《化学分析（中英对照版）》共分6章。第1章为概论，第2章为滴定分析法，第3～6章分别为酸碱滴定法、配位滴定法、氧化还原滴定法和重量分析法。
本书既可作为职业本科院校及高等职业专科学校资源环境、生物化工、食品药品等相关学科或专业的双语教材，也能作为普通本科学校相关专业教材，以及相关“走出去”企业员工本地化培养、“引进来”企业员工培训的教材，还可供其他专业师生及分析检验工作者参考。
本书第1～3章、第6章的中文内容及部分英文内容由兰州石化职业技术大学夏德强教授编写，第4章和第5章中文内容由安徽省宣城市环境监测中心夏海军高级工程师编写。本书英文部分的前言、第1章、第2章、第5章、第6章由兰州石化职业技术大学毛建梅翻译；第3章、第4章由兰州石化职业技术大学徐静老师翻译。兰州石化职业技术大学郑晓明、于娇娇、汪永丽、代学玉、柳樱华、张雅迪等老师参与了本书有关章节的审核校对、实验实训项目选题及课后习题的编写工作。全书由夏德强统稿并担任主编，毛建梅、夏海军担任副主编，兰州石化职业技术大学冷宝林教授任主审。
本书的编写参考了大量的相关教材、专著、论文、规范及标准等，尤其是书中部分插图引用了相关的国外教材，在此对本书所引用成果的单位和个人表示衷心感谢。
由于编者的知识和能力水平有限，书中不足之处在所难免，恳请广大师生、读者、专家批评指正，以便今后进一步修订。

PREFACE
In 2013， General Secretary Xi Jinping proposed the “The Belt and Road” initiative， which was actively responded by petroleum and chemical enterprises in China. During the period of the 13th Five-Year Plan， these companies accelerated the pace of globalization and kept enlarging their market share， so they played a crucial part in industrial chain， supply chain and value chain all over the world. However， the staff in the “global-oriented” enterprises， especially for those who work in petrochemical industry， urgently needs relevant teaching materials for training. Moreover， in October 2021， General Office of the CPC Central Committee and the General Office of the State Council issued the document entitled Opinions on Promoting the High-quality Development of Modern Vocational Education where it was clearly stated that a brand of vocational education with Chinese characteristics should be created by promoting Sino-foreign cooperation level in running schools， expanding exchange platforms between China and other countries as well as urging vocational education to go abroad， and then a number of professional curriculum standards and teaching resources with great international influence should be made. In view of the above-mentioned， in order to meet the needs of enterprise talent training and the requirements of the national vocational education reform and development， followed by the Vocational Education Law of the People’s Republic of China， writers and editors compiled the textbook of Chemical Analysis (Chinese-English Edition) & Instrumental Analysis (Chinese-English Edition) with the aims of highlighting vocational education’s features and emphasizing pragmatic under the guide of scientificity， advancement and applicability.
Chemical Analysis (Chinese-English Edition) is split up into 6 chapters. Chapter 1 and 2 are overviews of analytical chemistry and titrimetric analysis respectively; Acid-base titration， coordination titration， redox titration and gravimetric analysis are discussed from chapter 3 to 6 separately. This textbook can be used as a training material both for staff in local petrochemical industry with globalized intention and for employees of foreign enterprises in China. It can also be used as bilingual textbook for biology and chemical engineering， environmental protection and other related majors in Vocational Institutions for Undergraduates， Higher Vocational Colleges and Normal Undergraduate Universities.
The Chinese of the preface， chapter 1-3， chapter 6 in the textbook were written by Professor Xia Deqiang from Lanzhou Petrochemical University of Vocational Technology. Xia Haijun， Senior Engineer of Xuancheng Environmental Monitoring Center， was responsible for Chinese of chapters 4 and 5. Preface， chapter 1，2，5，6 were translated by Mao Jianmei. Chapters 3 and 4 were translated by Xu Jing. Xia Deqiang also served as the final editor， compiler and editor-in-chief of the book; Mao Jianmei and Xia Haijun served as deputy editors. Leng Baolin， Zheng Xiaoming， Yu Jiaojiao， Wang Yongli， Dai Xueyu， Liu Yinghua and Zhang Yadi participated in the proofreading selection of experimental training projects and compilation of after-class exercises.
The compilation of this coursebook takes a large number of related textbooks， papers， specifications and standards for reference， and I would like to extend my sincere and heartfelt thanks to the copyholders for generous permission to make use of the pieces here.
Suggestions for improvement will be gratefully received.
