Metal ion transport in maize: survival in a variable stress environment.

Maize (Zea mays) is the most widely cultivated crop in the world. Maize production is closely linked to the extensive uptake and utilization of various mineral nutrients. Potassium (K), calcium (Ca), and magnesium (Mg) are essential metallic macronutrients for plant growth and development.

The preparation of nano-MIL-101(Fe)@chitosan hybrid sponge and its rapid and efficient adsorption to anionic dyes.

The polymer adsorbents in the sponge form have the porous structure and high elasticity that endow them with good adsorption capacity and recyclability. The immobilization of nano-materials in the sponges can improve their adsorption properties evidently. The nano-MIL-101(Fe)@chitosan(CS) hybrid sponge was prepared by freeze-drying method.
