Wastewater from electroplating facilities and certain types of chemical plants contains toxic forms of hexavalent chromium such as chromate and dichromate. The hexavalent chromium in this wastewater must be reduced before the water can be discharged. This requires a two-step process: hexavalent chromium (CR6) is reduced to trivalent …
Applying phytoremediation in water purification had a promising prospect for environmental pollution.Phytoremediation is an acceptable, low-cost, easy-to-use, and common wastewater treatment method. This study aims to analyze the potential of phytoremediation for treating a combination of various wastewater in laboratory under …
The wastewater treatment techniques currently employed treat hexavalent chromium-containing effluent streams with low-cost industrial byproducts. Emphasis is on novel techniques of wastewater treatment electrochemical techniques for Cr (VI), contributing to various environmental problems based on their toxicity.
Therefore, advanced treatment of these types of wastewater is urgently needed. A cobalt/iron carbonate layered double hydroxide (Co 2 Fe 1-CO 3-LDH) was synthesised in this study as an adsorbent to remove chromium citrate complexes. After treatment, the total chromium could be reduced from 20.8 mg/L to less than 1.5 mg/L.
