Summary
This study optimized 1,4-dioxane degradation using Advanced Oxidation Processes (AOPs) and BAC-TERRA microbial complex. Pozzolan and photo-Fenton oxidation proved highly effective for 1,4-dioxane removal from wastewater.
Area of Science:
- Environmental Chemistry
- Water Treatment Technologies
- Bioremediation
Background:
- 1,4-dioxane is a persistent environmental pollutant often found in industrial wastewater.
- Effective degradation methods are crucial for mitigating its ecological impact.
- Both Advanced Oxidation Processes (AOPs) and biological treatments are explored for contaminant removal.
Purpose of the Study:
- To determine optimal decomposition conditions for 1,4-dioxane using AOPs and the BAC-TERRA microbial complex.
- To compare the efficacy of different treatment strategies, including UV/H2O2 and biological methods.
- To investigate the influence of suspended particles on degradation efficiency.
Main Methods:
- Advanced Oxidation Processes (AOPs) utilizing UV/H2O2 with varying concentrations and reaction times.
- Evaluation of suspended particles like bio-flocs, kaolin, and pozzolan in AOPs.
- Aerobic biological decomposition using the BAC-TERRA microbial complex.
- Kinetic analysis of degradation processes.
Main Results:
- AOPs achieved up to 96% 1,4-dioxane oxidation with 17 mM H2O2 in 2 hours.
- Pozzolan addition enhanced decomposition to 98.8% within 2 hours.
- Photo-Fenton oxidation (Fe(II):H2O2) completely degraded 1,4-dioxane in polyester wastewater within 15 minutes.
- BAC-TERRA removed up to 90% of 1,4-dioxane in 15 days, forming similar organic acid by-products.
Conclusions:
- 1,4-dioxane can be effectively degraded by both AOPs and BAC-TERRA.
- Photo-Fenton oxidation is a highly efficient method for treating industrial wastewater contaminated with 1,4-dioxane.
- The choice of treatment method depends on specific wastewater characteristics and desired removal rates.

01:46Oxidative Cleavage of Alkenes: Ozonolysis
In ozonolysis, ozone is used to cleave a carbon–carbon double bond to form aldehydes and ketones, or carboxylic acids, depending on the work-up.

02:04Oxidation of Alkenes: Anti Dihydroxylation with Peroxy Acids
Diols are compounds with two hydroxyl groups. In addition to syn dihydroxylation, diols can also be synthesized through the process of anti dihydroxylation. The process involves treating an alkene with a peroxycarboxylic acid to form an epoxide. Epoxides are highly strained three-membered rings with oxygen and two carbons occupying the corners of an equilateral triangle. This step is followed by ring-opening of the epoxide in the presence of an aqueous acid to give a trans diol.

02:44Oxidation of Alkenes: Syn Dihydroxylation with Osmium Tetraoxide
Alkenes are converted to 1,2-diols or glycols through a process called dihydroxylation. It involves the addition of two hydroxyl groups across the double bond with two different stereochemical approaches, namely anti and syn. Dihydroxylation using osmium tetroxide progresses with syn stereochemistry.
01:20Radical Autoxidation
The oxidation of an organic compound in the presence of air or oxygen is called autoxidation. For example, cumene reacts with oxygen to form hydroperoxide. Autoxidation involves initiation, propagation, and termination steps. Many organic compounds are susceptible to autoxidation—especially ethers in the presence of oxygen, which form hydroperoxides. Even though this reaction is slow, old ether bottles contain small amounts of peroxide, which leads to laboratory explosions during ether...
01:10Hydrolysis of Chlorobenzene to Phenol: Dow Process
Simple aryl halides do not react with nucleophiles under normal conditions. However, the reaction can proceed under drastic conditions involving high temperatures and high pressure to give the substituted products. For example, chlorobenzene is converted to phenol using aqueous sodium hydroxide at 350 °C under high pressure by the Dow process. The reaction follows an elimination-addition mechanism involving a benzyne intermediate. Here, the chloride ion is eliminated to generate the benzyne...
