“…Soil S2, which had similar retentions to S3, had slightly higher SOM than the other two soils. These results were consistent with previous findings [36,41,42] and support the notion that the main retention process was SOM-Cr(VI) redox reaction, followed by Cr(III) precipitation. While Fe(II)-mediated reduction rates increase with increasing pH for pH > 4 [26], SOM-mediated reduction is favored by acidic environments [20,21].…”

“…These data indicated that building mesocosms of bacterial communities was detected at the family level. After standardizing the number of sequences per sample at a 97 % OTU [27] cutoff, de-trended correspondence analyses of OTU matrices showed that the addition of nutrients and planting of plants in mesocosms had a strong and significant effect on bacterial community structures ( Table 2). A total of 11,705 OTUs were detected, of which 203 were shared between the four different mesocosms on day 30 (Fig.…”

Four pilot-scale test mesocosms were conducted for the remediation of organochlorine pesticides (OCPs)-contaminated aged soil. The results indicate that the effects on degradation of hexachlorocyclohexanes (HCHs) and dichlorodiphenyltrichloroethanes (DDTs) were in the following order: nutrients/plant bioaugmentation (81.18 % for HCHs; 85.4 % for DDTs) > nutrients bioaugmentation > plant bioaugmentation > only adding water > control, and nutrients/plant bioaugmentation greatly enhanced the degradation of HCHs (81.18 %) and DDTs (85.4 %). The bacterial community structure, diversity and composition were assessed by 454-pyrosequencing of 16S recombinant RNA (rRNA), whereas the abundance of linA gene was determined by quantitative polymerase chain reaction. Distinct differences in bacterial community composition, structure, and diversity were a function of remediation procedure. Predictability of HCH/DDT degradation in soils was also investigated. A positive correlation between linA gene abundance and the removal ratio of HCHs was indicated by correlation analyses. A similar relationship was also confirmed between the degradation of HCHs/DDTs and the abundance of some assemblages (Gammaproteobacteria and Flavobacteria). Our results offer microbial ecological insight into the degradation of HCHs and DDTs in aged contaminated soil, which is helpful for the intensification of bioremediation through modifying plant-microbe patterns, and cessation of costly and time-consuming assays.

“…Each type of the centres is described by the Langmuir isotherm equation, and the active sites are characterized by constants K 1 , b 1 and K 2 , b 2 , respectively (iv). Double Langmuir equation has been successfully applied to interpret results of metal adsorption by activated sludge [19,20] and to evaluate adsorption of metals in soils [14].…”

A study was undertaken to evaluate the efficiency of adsorption and desorption of three reactive dyes on to modified chitin. Black DN from the chlorotriazine group, Scarlet R from the vinylsulfone group of dyes and a chlorovinyl dye, Brilliantorange 3R, were examined. Following adsorption of the dyes at pH 3, their desorption was carried out at pH 11. The results obtained indicated that the highest efficiency of desorption, nearly 100%, was obtained for Brilliantorange 3R, and lower ones for Scarlet R and Black DN, at 89% and 90%, respectively. The highest number of adsorption/desorption cycles, nearly 100, was recorded for Brilliantorange 3R. In the case of Scarlet R the number of subsequent adsorption/ desorption cycles run reached around 25, whereas in the case of Black DN it accounted for 37.
