Water pollution by heavy metals and organic dyes has become a serious environment issue. Diverse technologies have been reported to eliminate these pollutants. Among these methods, nanoadsorbents are of particular interest in wastewater treatment because of their high surface-to-volume ratio, which leads to a higher uptake capacity. However, most of the reported nanoadsorbents are flow type, which are very vulnerable to leakage in the process of separation because they are dispersed or precipitated. It has been recently reported that the unintended leakage of nanomaterials into the environment can cause a significant threat to the environment and public health. Here, we report a janus sponge composite that can be partially floated/submerged on/in the water to perform efficient adsorption of pollutants without leakage of adsorbents. |
