Zinc biosorption by seaweed illustrated by the zincon colorimetric method and the Langmuir isotherm

The zincon colorimetric method to determine metal ions in solutions is suitable for analysis of both potable and polluted waters. The zincon colorimetric method is an easy technique for zinc assessment and adds an interesting motivational aspect to study zinc removal by the green algae and the red a...
