Kinetic and equilibrium studies of phenol adsorption by natural and modified forms of the clinoptilolite

Posidonia oceanica (L.) fibers as a potential low-cost adsorbent for the removal and recovery of orthophosphate

“…Many models are used to fit the kinetic sorption experiments. The most used ones are the pseudo-first order [19], pseudo-second order [20], intraparticle and film diffusion models [21]. The kinetic model and their linear forms are given in Table 1.…”

Variation in performance of surfactant loading and resulting nitrate removal among four selected natural zeolites

“…The target contaminants include heavy metals [13][14][15], organic pollutants [16][17][18][19], organic dyes in waste water [20], nutrients [21], and microbial pathogens [22]. To widely apply the use of SMZs for water treatment, knowledge of the surfactant loading performance of selected zeolites is very important.…”

Recovery of hydroxycinnamic acids from renewable resources by adsorption on zeolites

“…The effect of pH upon adsorption of phenolic compounds has already been related to the degree of ionization of the phenolic sorbate by various authors [33][34]. Davila-Guzman et al [29] also demonstrated that the adsorption capacity of ferulic acid decreased with a pH increase for XAD16.…”
