· The uranium-adsorbing abilities of seven plant wastes were investigated. High abilities to adsorb uranium from non-saline water 10 mg dm −3 of uranium were observed with a number of plant wastes tested. However, with seawater supplemented with 10 mg dm −3 of uranium, similar results were found only with chestnut residues. When the plant wastes were immobilized with

Balance the equation for the reduction of MnO4- to Mn2

In acidic , to balance H atoms you just add H + to the side lacking H atoms but in a basic , there is a negligible amount of H + present. Instead, OH- is abundant. In this case, you add H 2 O to the side lacking H atoms and a OH- to the opposite side
