低成本治疗的Cd (II) & Sn从产业废水(II)

文摘

文摘:印度的人均水资源可用性自1951年以来已经下降了70%,下降的速度预计将迅速增加,由于人口增长与生活方式的变化和气候变化的后果。印度的可持续的未来在于有效的水资源管理系统,尤其是废水的处理和回收。介绍一个社区友好切除治疗实践Cd (II)和Sn (II)从电镀废水产生和珠宝商的工作坊,水污染这两个有毒金属高。通过筛查研究找到廉价的重金属吸附剂,地面简而言之被发现是有效的对不同金属以不同的效率。在Cd (II)和Sn (II)材料发现是非常有效和效率发现不同颗粒大小的生物吸附剂。最大吸附与0.21毫米粒度记录。调查显示,删除Cd (II)和Sn (II)从水的解决方案依赖于接触时间,pH值、吸附剂用量,初始浓度的金属离子(吸附物)。雷竞技网页版最大吸附的Cd (II)和Sn (II)发生在酸碱6.0和2.0,分别。在不同的试验,最大吸附的Cd (II)和Sn (II)被记录在粒径0.210毫米,50毫克/毫升的吸附剂浓度在pH值为6.0和2.0,分别。现场研究表明57%的Cd (II)和82.5%的锡(II)从电镀行业废水。 The results of the study reveal that Ground nut can be effectively used for Cd (II) & Sn (II) removal from the electroplating effluent waters, by optimizing the technique in the field trials. Note: This work is presenting at 9 th International Summit on Global Warming and Environmental Science (Global Warming-2020 Webinar) on Aug 10-11, 2020. Biography : Prof P. V. V. Prasada Rao worked on Pollution Analysis, Remediation of wastes, Microbial ecology, Vegetation studies and on Environmental Impact Assessment. At present he is involved in the Apportioning of Particulate Matter in ambient air of Visakhapatnam, an important city in South India. He developed low cost methodologies for the removal of Heavy metals from Industrial effluents. He also worked on bio degradation of plastics, bio removal of Fluoride in ground water, Climate change studies and on development of Silver Nano particles for addressing metal pollutants in aqueous solutions. Good number of students are benefitted by the research studies of Prof. P. V. V. Prasada Rao. Dr. Rao published more than 85 scientific papers in both National and International Journals. He is at present working as a Prof. Head of the Dept. of Environmental Sciences, Andhra University, Visakhapatnam, India.
