Synthesis of irregular graphene oxide tubes using green

2017/9/21Micrometer length tubes of graphene oxide (GO) with irregular form were synthesised following facile and green metal complexation reactions. These materials were obtained by crosslinking of GO with calcium, zinc or strontium chlorides at three different temperatures (24, 34 and 55C) using distilled water as solvent for the compounds and following a remarkably simple and low-cost synthetic

Fast Removal of Sr(II) From Water by Graphene Oxide

Graphene oxide is a unique material that can be used for adsorption of radioactive waste because it contains various function groups such as epoxide, carbonyl, carboxyl and hydroxyl in addition to its high specific surface area. The as-prepared GO and the modified one (GO-chitosan composite) have been prepared then characterized and used as adsorbent for radioactive metal ions [Strontium, Sr

Selective Adsorption and Efficient Removal of Phosphate

A three-dimensional adsorbent, i.e., lanthanum oxide decorated graphene composite (3D graphene–La2O3 composite), is prepared. The composite exhibits favorable adsorption performance to phosphate, providing a sorption capacity of 82.6 mg g–1 at pH 6.2. The adsorption behavior for phosphate fits the Langmuir model, and the adsorption kinetics fit a pseudo-second-order model, with
