“…There is no difference among different mHCs for Cd adsorption. It is possible that the rate limiting step in adsorption of mHCs for Cd(II) is a chemical adsorption process rather than diffusion (Bai et al 2011). Figure 7 presents cadmium sorption isotherms for unmodified and KOH-modified hydrochars.…”

“…Tetraethyl orthosilicate: (Si(OC 2 H 5 ) 4 : TEOS, >99%) was purchased from SigmaAldrich (Sintra, Portugal), sodium hydroxide (NaOH) (>98%) was purchased from VWR Prolabo (Carnaxide, Portugal), ethanol (CH 3 CH 2 OH) (>99%) obtained from Panreac (Odivelas, Portugal) and ammonia solution (25% NH 3 ) obtained from Riedel-de-Häen (Sintra, Portugal). The certified standard solution of mercury nitrate (1000 ± 2 mg/L) was purchased from Merck (Carnaxide, Portugal).…”

“…exchange, adsorption, membrane filtration and electrochemical technologies [1]. Among these techniques, adsorption has been one of the most effective and simplest approaches developed for removal purposes [2][3][4][5]. The efficiency of the adsorption process is mostly affected by the properties of the adsorbent, namely the type of interactions occurring between the adsorbate and the sorbent's surfaces.…”

“…It has been reported that S atoms play the major role in complexation with Cd (Bai et al 2011). According to the theory of hard and soft acid-base, the soft acid Cd has strong binding activity with the soft base dithiocarbamates (Pearson 1963).…”
