Prepared PANI@nano hollow carbon sphere adsorbents with lappaceum shell like structure for high efficiency removal of hexavalent chromium

Adsorption of Rhodamine B on Spherical Activated Carbon synthesized from Waste Bagasse Liquid using Hydrothermal Process

“…This catalyst shows good selectivity for CO production. The unique composite adsorbent of polyaniline/nano hollow carbon sphere can also be synthesized by in-situ polymerization (Wang et al, 2021). This material can effectively adsorb the Cr(VI) and reduce it into Cr(III) which has low toxicity.…”

Synthesis of hollow spherical polyaniline by using poly(styrene‐co‐acrylic acid) sphere as the template for high adsorption of Cr(VI)

“…Its maximum adsorption capacity of Cr(VI) was 127.9 mg g −1 at pH = 3. Zhang 22 prepared a series of novel polyaniline@nano hollow carbon spheres of PANI@NHCS‐10, PANI@NHCS‐20, PANI@NHCS‐30 and PANI@NHCS‐40NHCS through in‐situ polymerization method. The maximum adsorption capacity of Cr(VI) for PANI@NHCS‐30arrived at 250.0 mgg −1 at pH = 1, 293 K. Currently, several hollow spherical polyanilines have been developed for adsorption of the Cr(VI) 23 .…”

Design of a paulownia-biochar/MoS2 composite electrode material for efficient electrosorption removal of Cr(vi) from wastewater

“…5 Due to the serious harm caused by chromium to human health, many countries and regions have lowered the content standard of Cr(VI) in drinking water to 0.05 mg L À1 issued by the World Health Organization. 6 The methods commonly used to remove chromium ions from wastewater include photocatalytic reduction, physicalchemical adsorption, chemical precipitation, biological methods, etc. [7][8][9][10] However, there are certain limitations in these processing methods.…”
