Comprehensive and critical appraisal of plant-based ...

Furthermore, various published articles in which plant-based adsorbents augmented the removal of fluoride from water resources unravelled the factors that accelerated the pace of defluoridation (George and Temburkar, 2018; Ravulappalli and Kunta, 2017; Suneetha et al., 2015). Mostly plant-based adsorbents showed the best removal rate at pH 7.
