Hazardous industrial wastes negatively impact the environment by creating issues for aquatic as well as human's life. This study investigates the treatment of hazardous industrial wastewater using cost-effective graphite adsorbent along with electrochemical regeneration integrated with renewable solar energy. The synthetic industrial effluent containing crystal violet dye was treated using an adsorbent (Nyex™ 1000) having a surface area of 1.0 m g . The efficiency of removing solute was found to be more than 90%. The adsorbent regeneration efficiency was achieved at 99.5% by passing a charge of 100 C g at current density of 10 mA cm for 1 h. Solar energy was integrated with electrochemical reactor for the regeneration of adsorbent to make the system cost-effective and self-sustainable. PRACTITIONER POINTS: Industrial hazardous wastewater treatment with a cost-effective graphite integrated adsorbent. Development of renewable solar energy-integrated with electrochemical system for regeneration. Regeneration efficiency of adsorbent Nyex™ 1000 was achieved around 99.5% with integrated system. Sustainable system was introduced to incorporate with renewable energy for waste water treatment.
危险工业废物通过对水生生物和人类生命造成问题，对环境产生负面影响。本研究探讨了使用具有成本效益的石墨吸附剂以及与可再生太阳能集成的电化学再生来处理危险工业废水。使用表面积为 1.0 m g 的吸附剂（Nyex™ 1000）处理含有结晶紫染料的合成工业废水。发现去除溶质的效率超过 90%。通过在 1 小时内以 10 mA cm 的电流密度施加 100 C g 的电荷，可实现吸附剂的 99.5%再生效率。将太阳能与电化学反应器集成，用于吸附剂的再生，使系统具有成本效益和自可持续性。
