Abstract：
Eradication of heavy metal pollution has become the prime priority over the conservation of water resources in the upcoming era. Herein, the study involved the halophilic fungal melanin from Curvularia lunata showed a promising biosorbent for the removal of toxic heavy metals which shows eco-friendly, cost-effective, high stability, and adsorbent efficiency. Polyurethane blended with fungal melanin polymers, makes polymeric nanofibrous membranes through electrospinning techniques. BET isotherms revealed the raw fungal melanin holds a surface area of 3.54 m2/g exhibiting type IV isotherms. BJH results in a total pore volume of 5.79 cc/g with a pore diameter of 6.54 ± 1 nm for pores smaller than 4544.8 Å. Exhibits Eumelanin properties were characterized by FE - SEM and FTIR functional elements. ICPMS confirmed the metal adsorption proficiency on both raw and melanized membranes before and after treatments. Over 17 heavy metals, Ni2+ were adsorbed with 100% efficiency by raw melanin alone with 42.48 µg/L of Ni2+ concentration in the water sample, whereas, Cu2+, Zn2+, Co2+, Cr2+, Pb2+, Mn2+, Al3+, Mo6+, Sb3+, Ba2+, Fe2+, and Mg2+ stands next with 99%. In this study, gentle/simple application of raw fungal melanin (without PUR tailored) can detoxify the maximum concentration of heavy metals present in the water bodies which are further used for irrigation and even drinking purposes. This mycoremediation approach can be easily adapted to industrial production than other high-performance membrane materials with minimal process modification, making it a promising strategy for improving the adsorption properties used in various applications after still furthermore investigation.
摘要：
在即将到来的时代，消除重金属污染已成为保护水资源的首要任务。在这里，这项研究涉及来自弯孢菌的嗜盐真菌黑色素，显示出一种有前途的生物吸附剂，用于去除有毒重金属，显示出生态友好，成本效益高,高稳定性,和吸附效率。聚氨酯与真菌黑色素聚合物混合，通过静电纺丝技术制造聚合物纳米纤维膜。BET等温线显示，原始真菌黑色素的表面积为3.54m2/g，表现出IV型等温线。BJH的总孔体积为5.79cc/g，小于4544.8的孔的孔径为6.54±1nm。通过FE-SEM和FTIR功能元素对样品Eumelanin的性质进行了表征。ICPMS证实了处理前后在原始膜和黑色素化膜上的金属吸附能力。超过17种重金属，单独的原始黑色素以100％的效率吸附Ni2，水样中的Ni2浓度为42.48µg/L，然而,Cu2+,Zn2+,Co2+,Cr2+,Pb2+,Mn2+,Al3+,Mo6+,Sb3+,Ba2+,Fe2+,和Mg2+接下来是99%。在这项研究中,温和/简单地施用原始真菌黑色素（没有PUR定制）可以使水体中存在的重金属的最大浓度解毒，这些重金属进一步用于灌溉甚至饮用目的。与其他高性能膜材料相比，这种真菌修复方法可以轻松适应工业生产，只需最少的工艺修改，在进一步研究之后，使其成为改善各种应用中使用的吸附性能的有前途的策略。
