1. Introduction
Fullerene and its derivatives have gained immense attention so far due to their remarkable properties and potential applications in many areas, including environmental remediation (e.g., adsorbents and catalysts) (Yang et al., 2006; Meng et al., 2012), biomedicine (e.g., antibacterial and antitumor) (Markovic and Trajkovic, 2008; Kwag et al., 2013), and materials science (e.g., sensors, supercapacitors, and hydrogen storage) (Li et al., 2009; Xiong et al., 2012; Rather and De Wael, 2013). With the ever-increasing production and wide applications of fullerene-based carbon nanomaterials, they will inevitably enter into the environment (Colvin, 2003; Klaine et al., 2008). As such, significant concerns have been drawn to their influences on human health and natural environment. Although fullerene is highly hydrophobic, water-soluble fullerenes, such as aqueous fullerene colloid aggregates (nC60) and polyhydroxy fullerene (PHF), can be conveniently synthesized by ultrasonication, solvent exchange, and chemical modification (Brant et al., 2006; Georgieva et al.,2013). The enhanced water-solubility expands their applications, but may simultaneously increase their risks to the environment and human health (Klaine et al., 2008). Indeed, the cytotoxicity of water-soluble fullerenes to both bacteria and human cell has been confirmed by many studies (Sayes et al., 2004; Wielgus et al., 2010; An and Jin, 2012). Consequently, proactive research on effective removal of water-soluble fullerenes from aqueous solution is critical to controlling the potential risks and ensuring a sustainable carbon nanomaterials industry. At present, a number of studies have been conducted to remove nC60 from wastewater by various adsorbents, such as biomass (Kiser et al., 2010), activated sludge (Yang et al., 2013), and alum (Wang et al., 2013). In contrast, much less work about the pollution control of PHF has been reported up to now. On the other hand, Prylutskyy et al. (2014) indicated that the origin of fullerene solubility in water was probably based on the surface hydroxylation of fullerenemolecules; therefore, nC60 could be considered as fullerene aggregates with a certain amount of hydroxyls on the outer surfaces. Furthermore,when exposed to the environment, fullerenes and nC60 could be transformed into PHF by many factors (e.g., long-term mixing, ultraviolet radiation, and interaction with microbes and oxidants) (Hwang and Li, 2010; Qu et al., 2010; Chae et al., 2014). Hence, being regarded as the main products of fullerenes in the environment, PHF need large concerns in terms of their pollution control
