Chemical experiment is one of the important means of chemical research and teaching,which provides an important basis for the development of chemical science and the progress of subject teaching.In the current era with rapid development of science and technology,more and more new materials are found in chemical experiments,promoting the development of leading-edge science while enriching people's daily life.However,under the background of a risk society,the risk of chemical experiments has also appeared along with the advancement of experiments,which is an issue that experimenters need to think about and avoid.This paper defines the risk and characteristics of chemical experiments,analyzes numerous contributing factors,elaborates its formation mechanism,proposes corresponding avoidance measures aiming to the risk of chemical experiments,and concretely analyzes the formation and evasion of chemical experiment risk taking the chemical synthesis experiment of graphene as an example.The paper is divided into six chapters.The first chapter proposes research questions and carries on theliterature review on current status.The second chapter analyzes the essence of chemical experiment risk and its characteristics of uncertainty,human property,harmfulness and systematization.The third chapter analyzes the causative factors of chemical experiment risk from three aspects of experimental cognition,practice,mediation of chemical experiment and the social environment.The fourth chapter systematically discusses the formation mechanism of chemical experiment risk from both internal and external aspects.In the fifth chapter,according to the formation process of chemical experiment risk,the avoidance countermeasures for chemical experiment risk are proposed for the experimenter,the public and the government.In the sixth chapter,taking the chemical synthesis experiment of graphene as an example,the risk factors,formation mechanism and avoidance countermeasures are analyzed.
