Due to the characteristics of the stable oil–water emulsions, it requires more costly and complicate treatment techniques to remove oil from spent MWFs. Metal organic frameworks(MOFs) are a porous network material used to remove contaminants from environment. One of the most prominent of MOFs is HKUST-1 or Cu-BTC. In this study, the Cu-BTCs were prepared by solvothermal method in various conditions and used as absorbent for removing oil micelles in MWF emulsion. The particle size of all synthesized Cu-BTCs ranged from ≈80 to 400 nm. The ability of all synthesized Cu-BTCs to remove oil micelle was greater than 95% in 60 min, while the capacity of GAC was obtained the result for only 6.8%. The maximum adsorption capacity(q _(max)) of oil micelles on Cu-BTCs was 1666.7 mg·g^(-1). The highest removal capacity of oil micelles in MWF emulsion is greater than 99% in 24 h by using Cu-BTCs washed with either butanol or ethanol.展开更多

Intelligent manufacturing technology ...Intelligent manufacturing is the inevitable requirement of the development of manufacturing industry to a certain stage, and it is the development trend of industry in the future. Intelligent manufacturing technology and system is the core of intelligent manufacturing. Based on modern sensing technology, network technology, automation technology and artificial intelligence technology, it makes the product design process, manufacturing process, enterprise management and service intelligent by means of perception, man-machine interaction, decision-making, execution and feedback. Nowadays, the world is experiencing a great change that has never happened in a hundred years. The fourth industrial revolution is unprecedentedly fierce, and the development momentum of intelligent manufacturing is strong, which has become the trend of global manufacturing development. New production methods, new industrial forms and new business models are constantly emerging.展开更多
