The　modified　cellulose　magnetic　microsphere　is　magnetized　on　the　modified　cellulose.　It　combines　the　properties　of　the　modified　cellulose　and　the　advantages　of　the　magnetic　adsorption　technology　together.　This　paper　summarizes　the　method　of　preparation　of　modified　cellulose　magnetic　microsphere　and　application　of　its　adsorption　of　heavy　metal.　Further,　this　article　raises　the　improvement　methods　to　obtain　the　better　performance　of　the　finished　product,　thereby　enhancing　the　cellulose　adsorbent　flexibility　and　breadth　of　application.
