Controllable Preparation and Applications of Alginate Microcapsules and Nano-Fe3O4: Introduce a Comprehensive Exploratory Experiment

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.
