“…41 The Freundlich and Langmuir isotherm equations can be converted to a linear form to determine the values of characteristic isotherm constants. 42 The calculated parameters for Langmuir and Freundlich isotherm models are given in Table 1. The results showed that the equilibrium data fitted the Langmuir isotherm model well at the temperature range from 20 to 40°C.…”

The study investigated the performance of tannin adsorption on treated coal fly ash. The adsorption capacity of coal fly ash could be enhanced through appropriate pretreatment by acid. There was an apparent increase of tannin adsorption when fly ash dosage changed from 0 to 20 g/L. The adsorption isotherm data fitted to Freundlich and Langmuir models. The adsorption process followed pseudo-second-order kinetics. The adsorption processes presented a two-stage pattern, a rapid adsorption process followed by a slow adsorption process. The adsorbed amount of tannin was higher at 20°C than other temperature levels. The thermodynamic studies indicated the adsorption of tannin onto fly ash was exothermic in nature and the entropy of the system decreased during adsorption process. The removal efficiency of tannin adsorption onto fly ash decreased when NaCl concentration ranged from 0 to 0.4 mol/L.

“…[14]. An et al analyzed performance of mesophilic anaerobic granules for removal of octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine (HMX) from aqueous solution [15]. However, there is little information on enhancing the biosorption capacity of porous anaerobic granules by surface modification.…”

“…On the one hand, the relative microorganisms must take up the available carbons, nutrients and electrons such as volatile fatty acids (VFAs), carbohydrates and H 2 , to replenish their intracellular pools prior to initiating biological activities . On the other hand, the inorganic anions such as sulfate and nitrate, which often co‐existed with NACs in industrial wastewaters, can also act as external electron acceptors to compete electrons with the reduction of nitro group .…”

Two lab‐scale anaerobic sequence batch reactors (ASBRs), respectively fed with 5 mg L−1 (R1) and 200 mg L−1 (R2) of sulfate were set up in this study. A mixture of the volatile fatty acids (VFAs) containing acetate and propionate was provided as electron donors. The effects of the influent nitrobenzene (NB) concentrations and the external electron acceptor of sulfate on the operational performance of ASBRs were investigated. The results indicated that NB reduction, sulfate reduction and propionate degradation were inhibited or further terminated in response to a shocked influent NB concentration of 50 mg L−1, i.e., 32 g m−3 day−1. However, these biological activities in ASBRs could be reversibly resumed so long as the influent NB regained below 30 mg L−1. The insufficient propionate was the main electron donor for the simultaneous reductions of NB and sulfate. Sulfate can energetically compete with NB for propionate as a co‐substrate, resulting in the better performance of reactor R1 than that of R2. In engineering applications, the influent loading rates of pollutants should be safely declined below toxic thresholds to avoid the failure of system operation. © 2017 American Institute of Chemical Engineers Environ Prog, 37: 712–718, 2018
