| 1 | Adsorption of pharmaceuticals from aqueous solutions using biochar derived from cotton gin waste and guayule bagasse显示文摘Biochars produced from cotton gin waste(CG)and guayule bagasse(GB)were characterized and explored as potential adsorbents for the removal of pharmaceuticals(sulfapyridine-SPY,docusate-DCT and erythromycin-ETM)from aqueous solution.An increase in biochar pyrolysis temperature from 350οC to 700℃ led to an increase in pH,specific surface area,and surface hydrophobicity.The electronegative surface of all tested biochars indicated that non-Coulombic mechanisms were involved in adsorption of the anionic or uncharged pharmaceuticals under experimental conditions.The adsorption capacities of Sulfapyridine(SPY),Docusate(DCT)and Erythromycin(ETM)on biochar were influenced by the contact time and solution pH,as well as biochar specific surface area and functional groups.Adsorption of these pharmaceutical compounds was dominated by a complex interplay of three mechanisms:hydrophobic partitioning,hydrogen bonding andπ-πelectron donor-acceptor(EDA)interactions.Despite weakerπ-πEDA interactions,reduced hydrophobicity of SPY−and increased electrostatic repulsion between anionic SPY−and the electronegative CG biochar surface at higher pH,the adsorption of SPY unexpectedly increased from 40% to 70% with an increase in pH from 7 to 10.Under alkaline conditions,adsorption was dominated by the formation of strong negative charge-assisted H-bonding between the sulfonamide moiety of SPY and surface carboxylic groups.There seemed to be no appreciable and consistent differences in the extent of DCT and ETM adsorption as the pH changed.Results suggest the CG and GB biochars could act as effective adsorbents for the removal of pharmaceuticals from reclaimed water prior to irrigation.High surface area biochars with physico-chemical properties(e.g.,presence of functional groups,high cation and anion exchange capacities)conducive to strong interactions with polar-nonpolar functionality of pharmaceuticals could be used to achieve significant contaminant removal from water. | Marlene C.Ndoun Herschel AElliott Heather EPreisendanz Clinton FWilliams Allan Knopf John EWatson | 2021 | Biochar2021，3，1： | 3 |
| 2 | Growth and Photosynthesis Responses of a Super Dwarf Rice Genotype to Shade and Nitrogen Supply显示文摘Specific aspects of plant cultivation require tests under fully controlled environmentalconditions with restricted energy supply, such as orbit-based space laboratories and low-light conditions.For these growing conditions, super dwarf plants have been developed as model crops, and a gibberellindeficientSuper Dwarf Rice genotype was proposed as a model crop for space flight plant experiments.We tested this genotype in a climate chamber experiment under different illumination and nitrogen supplylevels to assess its suitability under scenarios with limited resource availability. A 25% reduction inillumination led to a 75% reduction in yield, mainly due to a 60% reduction in formed tillers and 20%reduction in grain weight, and a 80% reduction in illumination caused total yield loss. Leaf area underreduced illumination was significantly lower, and only marginal changes in the dimensions of leaves wereobserved. Plant photosynthesis was not significantly different between control and 75% illumination. Thiswas explained by a higher photochemical efficiency under lower light conditions and a reduced mesophyllresistance. Therefore, we concluded that this genotype is well-suited for plant experiments under spaceand light-limited conditions since it kept its small stature and showed no shade avoidance mechanisms,such as leaf elongation, which would complicate experiments under low-light conditions. Nitrogenconcentrations of 2.8 and 1.4 mmol/L led to no differences in plant growth. We concluded that a nitrogenconcentration of 1.4 mmol/L is sufficient for this genotype under the light intensities. | Marc SCHMIERER Oliver KNOPF Folkard ASCH | 2021 | Rice science2021，28，2： | 2 |
