Sorption based easy-to-use low-cost filters derived from invasive weed biomass for dye contaminated water cleanup

Abstract

Today, the development of functional nanostructured materials with specified morphologies utilizing environmentally friendly techniques is a very appealing topic in materials chemistry.

A sustainable waste plastic valorisation: conversion of discarded polyurethane into an active micro-cleaner using a DES system

“…Using eqn (2), the quantity of MG adsorbed at equilibrium, qe (mg g −1 ), was determined.Here, M is the dry mass of the adsorbates used in the solution, and V is the volume of the adsorbates. 29…”

“…The recovery experiment employed 10 mg of the PUC-2 material in 10 mL of a 5 mg L −1 dye solution with a 10-hour contact period at pH 8.5, and 2 mL of ethanol to renew the adsorbent after washing, filtering, and drying. 29…”

“…Here, M is the dry mass of the adsorbates used in the solution, and V is the volume of the adsorbates. 29…”

Nanocomposite-based high-performance adsorptive water filters: recent advances, limitations, nanotoxicity and environmental implications

“…As a result, researchers have lately sought to immobilize active metal composites on macro templates through electrostatic interaction or adsorption. 147 However, these methods are still limited to lab-scale demonstration. In summary, various nanocomposite-based membranes which exhibited notable separation efficiency for different kinds of pollutants are listed in Table 1.…”

Cannabis Weed Biomass Adsorbent for Batch Adsorption of Ro16 Dye From Aqueous Solution

“…Several adsorbents have been used for dyes and organic pollutants adsorption from aqueous solutions such as sawdust ( derived from invasive weed biomass of Parthenium hysterophorus (Kamath et al, 2022), and invasive plant biowaste (Nguyen et al, 2022). The invasive plant species cause huge economic losses to agriculture productivity, for instance, in India yearly monetary loss of US$ 16.8 billion to agriculture (Bang et al, 2022), therefore this pose a serious threat to the agricultural economy worldwide (Paini et al, 2016).…”
