Carbohydrate biopolymers, lignin based adsorbents for removal of heavy metals (Cd2+, Pb2+, Zn2+) from wastewater, regeneration and reuse for spent adsorbents including latent fingerprint detection: A review

Biotechnology Reports, Journal Year: 2021, Volume and Issue: 30, P. e00609 - e00609

Published: March 21, 2021

Living organisms are created by carbohydrate biopolymers such as chitosan, carboxymethyl cellulose, alginate and lignin. These have been extensively used for environmental applications because they bio-degradable, bio-compatible, non-toxic inexpensive. Recently, to prepare different nanocomposite adsorbents treatment of wastewater. explored the removal effectiveness inorganic pollutants from aqueous solution. This review article discusses synthesis application lignin nanocomposites heavy metals. Toxic metals can be efficiently absorbed cross-linkers, distributed in solutions divalent metal ions examine their polymer absorption capacity. were adsorption highly toxic Cd2+, Pb2+ Zn2+ water. To make ion uptake more effective, functionalization has implemented blending, grafting, or mixing with nanomaterials an extra functional group. The integration second part into main chain not only adds functionality but also increases mechanical efficiency, one core criteria adsorbent recyclability. remediation method wastewater is cheaper long reused. Furthermore, exhibited good performance reuse spent after adsorption-desorption processes including latent fingerprint detection using powder dusting method. Chitosan, based demonstrated better activities due great physical chemical properties chelation water higher regeneration various eluents several desorption-adsorption cycles. In addition, discussed. Finally, this makes recommendations future studies light environmentally favourable economical applications.

A hydrate-based zero liquid discharge method for high-concentration organic wastewater: resource recovery and water reclamation

npj Clean Water, Journal Year: 2023, Volume and Issue: 6(1)

Published: June 28, 2023

Abstract High-concentration organic wastewater has become a great challenge for treatment due to its toxicity and non-biodegradability. Traditional water methods focus on removing or destroying pollutants rather than considering the high-concentration as resource. As an ambitious sustainability goal, resource recovery from achieve zero liquid discharge (ZLD) attracted widespread attention. Here, hydrate-based method is proposed treat textile facilitate reuse of dyes enhance reclamation. The mechanism interaction between hydrate was invested. results show that are rejected growing lattice concentrated in residual solution. This can max removal efficiency 93.6% production rate 80%. In range 0–2000 mg/L, concentration does not affect effect rate. dye be reused again. exhibits potential recovering clean while achieving ZLD.
