TL;DR: Sawdust, a relatively abundant and inexpensive material is currently being investigated as an adsorbent to remove contaminants from water as discussed by the authors, and chemical substances including dyes, oil, toxic salts and heavy metals can be removed very effectively with the organic material.

TL;DR: Locally available sawdust, a byproduct of the world industry, was found to be a low cost and promising adsorbent for the removal of copper(II) from wastewater and provides strong evidence to support the hypothesis of adsorption mechanism.

TL;DR: The experimental result inferred that chelation ion exchange is one of the major adsorption mechanisms for binding metal ions to the maple sawdust.

TL;DR: The results indicate the potentially practical value of this method in industries and also provide strong evidence to support the adsorption mechanism proposed.

TL;DR: The experimental results provided evidence for chelation ion exchange as the major adsorption mechanisms for binding metal ions to the sawdust and an empirical relationship has been obtained to predict the percentage Nickel (II) removal at any time for known values of sorbent and initial sorbate concentration.

TL;DR: It is evident from a literature survey of about 210 recent papers that low-cost sorbents have demonstrated outstanding removal capabilities for certain dyes, and chitosan might be a promising adsorbent for environmental and purification purposes.

TL;DR: From a comprehensive literature review, it was found that some LCAs, in addition to having wide availability, have fast kinetics and appreciable adsorption capacities too.

TL;DR: It is evident from a literature survey of about 185 recently published papers that low-cost adsorbents have demonstrated outstanding removal capabilities for MB, and these include agricultural wastes, industrial solid wastes, biomass, clays minerals and zeolites.

TL;DR: The sorption capacities of commercial developed carbons and other low cost sorbents for chromium remediation are provided, and particular attention is paid to comparing the sorption efficiency and capacities of commercially available activated carbons to otherLow cost alternatives.

TL;DR: In this article, the authors provided the scattered available information on various aspects of utilization of the agricultural waste materials for heavy metal removal, which can be exploited for high efficiency and multiple reuse to enhance their applicability at industrial scale.
