Abstract:

A comprehensive exploratory experiment, preparation of calcium alginate microcapsules and nano-Fe3O4 is introduced to explore the effect of adsorbing organic matter and metal ions in water. This experiment is in line with the cutting-edge science development, which can fully stimulate students' interest in learning, and change passive learning into active learning. It is very conducive to improving students' comprehensive inquiry ability.

Key words: Comprehensive exploratory experiment, Nano-Fe3O4, Alginate microcapsules, Sewage treatment
