Adsorption behavior of Zn(II) on calcinated Chinese loess

Comparing the adsorption and desorption characteristics of 17α-ethinylestradiol on sludge derived from different treatment units

“…3.3556, R 2 = 0.9992. However, the EE 2 removal efficiency increased A similar phenomenon was observed in Zn (II) adsorption to Chinese loess, and the adsorption amount decreased from 69 to 18 mg/g with the increase in soil concentration from 2 to 10 g/L (Tang et al 2009). With increase in sludge concentration, the hydrolysis radius of sludge particles became less due to chemical interactions, such as flocculation and the overlap of the hydrolysis layers between colloid particles, which led to the reduction of effective adsorption sites for the same amount of sludge and decreased the unit adsorption capacity.…”

Study on the sorption process of triclosan on cationic microfibrillated cellulose and its antibacterial activity

“…In this study, in view of the high surface energy (Tang, Li, & Song, 2006) and positive charge of CMFC, pseudo-first-order and pseudosecond-order kinetic models (Ho, McKay, Wase, & Forster, 2000;Ofomaja, 2008;Tang, Li, & Chen, 2009) were used to determine the controlling mechanism of TCS sorption on CMFC.

RETRACTED: Designed pendant chain covalently bonded to analogue of heulandite for removal of divalent toxic metals from aqueous solution: Thermodynamic and equilibrium study

“…6c. Based on such ability of the pendant groups attached to the inorganic backbone in coordinating these metallic cations [27][28][29], the quantity can be related to N max f , which presented the values 7.47, 9.83, and 12.93 mmol g À1 for Co(II), Ni(II), and Cu(II), respectively, and the percentage removal (R e ) for each divalent metal (see Table 2). …”
