9Rice Husk Bio-Chars as Adsorbent for Methylene Blue and Ethinylestradiol from Water显示文摘Biobased adsorbents are eco-friendly materials used for water and wastewater treatment and air cleaning.This research work explores the potential use of rice husk chars as a low-cost adsorbent for pollutants from water,such as methylene blue and ethinylestradiol.Rice husk chars are prepared by combustion of rice husks(RH-Char)or pre-treated rice husks(PT-Char).A third char(M-Char)supplied by a local company which uses rice husks as combustion material is also studied.The chars are characterized by field emission scanning electron microscopy(FE-SEM)in conjunction with energy dispersive X-ray spectroscopy(EDX),X-ray powder diffraction(XRD),and zeta-potential measurements.The three bio-chars are tested as adsorbent for the removal of two wastewater contaminants:methylene blue(MB)and ethinylestradiol(EE2).According to the results,RH-Char and PT-Char present zeta-potential values near−52 mV,whereas M-Char shows a zeta-potential value of−32 mV.Both RH-Char and PTChar are rich in amorphous SiO_(2) and M-Char has crystalline SiO_(2)(cristobalite).The bio-chars remove MB and EE2 efficiently showing the following results for the adsorption capacity of MB(inμmol g^(−1)):769.2(RH-Char),41.2(PT-Char),and 31.7(M-Char).The adsorption capacity values for EE2(inμmol g^(−1))are:33.1(RH-Char),19.1(PT-Char),and 16.9(M-Char).The information gathered in the present work evidences the potential of rice husks bio-chars for bio-remediation and may in future contribute to the conversion of a side-stream from the rice industry into value-added materials.Jonathan Lacuesta Iris Beatriz Vega Erramuspe Liji Sobhana Dennis Kronlund Jouko Peltonen Soledad Gutiérrez Pedro Fardim 2020Journal of Renewable Materials2020,8,3:0
10Valorization of Aloe barbadensis Miller. (Aloe vera) Processing Waste显示文摘Aloe vera plant is known worldwide for its medicinal properties and application in gel-based products such as shampoo,soap,and sunscreen.However,the demand for these gel-based products has led to a surplus production of Aloe vera processing waste.An Aloe vera gel processing facility could generate up to 4000 kg of Aloe vera waste per month.Currently the Aloe vera waste is being disposed to the landfill or used as fertilizer.A sustainable management system for the Aloe vera processing waste should be considered,due to the negative societal and environmental impacts of the currents waste disposal methods.Therefore,this review focuses on various approaches that can be used to valorize Aloe vera waste into value-added products,such as animal and aquaculture feeds,biosorbents,biofuel and natural polymers.Researchers have reported Aloe vera waste for environmental applications biosorbents used for wastewater treatment of various pollutants.Several studies have also reported on the valorization of Aloe vera waste for production of biofuels such as bioethanol,mixed alcohol fuels,biogas and syngas.Aloe vera waste could also be valorized through isolation and synthesis of natural polymers for application in wound dressing,tissue engineering and drug delivery systems.Aloe vera waste valorization was also reviewed through extraction of value-added bioactive compounds such as aloe-emodin,aloin and aloeresin.These value-added bioactive compounds have various applications in the cosmetics(non-steroidal anti-inflammatory,tyrosinase inhibitors)and pharmaceutical(anticancer agent and COVID 19 inhibitors)industry.Jeltzlin Semerel Nigel John Wim Dehaen Pedro Fardim 2023Journal of Renewable Materials2023,11,3:0
11渗透性颜料涂料纸表面化学组分对UV光油吸收性的影响显示文摘采用碳氟化合物、有机硅化合物及碳氢化合物的等离子体涂层对渗透性颜料涂料纸进行表面改性,并研究其对UV光油吸收性的影响。通过水银孔隙率法的测试结果,得出等离子体涂层对纸张多孔结构没有影响的结论。采用X射线光电子能谱(XPS)和飞行时间二次离子质谱(ToF-SIMS)表征3种等离子体涂层的表面化学组分。碳氟化合物的等离子体涂层使UV光油接触角得到明显增加,而碳氢化合物的等离子体涂层对UV光油接触角没有明显的影响。当UV光油应用于一个存在压印力的凸版印刷单元时,表面化学组分的作用似乎变得很小。另外,本文还研究了在有无外部压力的情况下,UV光油黏度对吸收率的影响。Maiju Pyknen Kenth Johansson Roger Bollstrm Pedro Fardim Martti Toivakka 李兴存 2010中国印刷与包装研究2010,,3:0
