2008 journal article

Photocatalytic degradation of lignin using Pt/TiO2 as the catalyst

CHEMOSPHERE, 71(5), 998–1004.

By: Y. Ma*, C. Chang*, Y. Chiang*, H. Sung* & A. Chao n

author keywords: ADML; DOC; lignin; photocatalyst; Nernst type model; pseudo-first order kinetics
MeSH headings : Catalysis; Hydrogen-Ion Concentration; Kinetics; Lignin / chemistry; Oxygen / analysis; Photochemistry; Platinum / chemistry; Titanium / chemistry; Waste Disposal, Fluid / methods
TL;DR: The investigation indicated that the photocatalytic degradation rates could be enhanced 1-6 times faster after doping TiO(2) with Pt in different pH cases and the developed equation can be used to predict the color removal efficiency of lignin wastewater by the photoc atalytic process.

Decolorizing of lignin wastewater using the photochemical UV/TiO2 process

CHEMOSPHERE, 56(10), 1011–1017.

By: C. Chang*, Y. Ma, G. Fang*, A. Chao n, M. Tsai* & H. Sung*

author keywords: photochemical oxidation; color removal; ADMI; DOC; ORP
MeSH headings : Color; Hydrogen-Ion Concentration; Lignin / chemistry; Models, Chemical; Oxidation-Reduction; Photochemistry; Spectrophotometry; Time Factors; Titanium / chemistry; Ultraviolet Rays; Waste Disposal, Fluid / methods; Water Purification / methods
TL;DR: The data obtained in this study demonstrate that the UV/TiO2 process is effective in oxidizing the lignin thus reducing the color and DOC of the wastewater treated, and can achieve better removal of DOC and color than the UV treatment alone. (via Semantic Scholar)
