“…Thus this paper proposes that success of surfactants should not be judged on the basis of technical aspects, i.e. bioremediation processes alone, but also on biodegradation [7][8][9][10][11] and toxicity [10,12].…”

Triton X‐100 applications as surfactant raises concern on water and soil environment due to its non‐biodegradability and inhibition effect. This paper aims at reviewing Triton X‐100 biodegradability and inhibition literature. It shows Triton X‐100 is biodegradable by aerobic and anaerobic municipal wastewater sludge and Vibrio cyclitrophicus‐sp‐Nov organism. Adsorption and biodegradation are mechanisms of Triton removal. Triton inhibits anaerobic sludge organisms and some single aerobic organisms. Inhibition mechanisms are substrate shortage, physiological membrane‐damaging and/or alteration in organism cell membrane. Thus Triton X‐100 fate in the environment and its sustainable application can be controlled via proper selection of organism type, Triton concentration, and substrate.

This work aims to study the effect of contaminated soil remediation on some soil properties. Also a remediation experiment was conducted to show the useful effect of two remedies named Triton x-100 and potassium oleate in decreasing the hydrocarbons (aliphatic and aromatic) and heavy metals contents in crude oil contaminated soil samples. Two soils (sandy and calcareous) were contaminated by 1 , 2 and 3 % V/W of crude oil, then each contamination level was treated by 0 (untreated) , 1 and 3 % of the two used remedies. Pots were seeded with barley seeds, barley plant samples were collected at the end of the experiment. The total concentrations of nitrogen, phosphorus and potassium in plant samples and soil under study were estimated. Also, the concentration of hydrocarbons and heavy metals were measured. It can be deduced from the data obtained from this study that the total contents of nitrogen, phosphorus and potassium were significantly affected by contamination by crude oil. Application of Triton x-100 and potassium oleate decreased to high extents the concentrations of aliphatic and aromatic hydrocarbons as well as the heavy metals. For example, the use of Triton x-100 reduced the concentration of aliphatic hydrocarbons by percents reached to 54 % as compared to the non-remedied samples. On the other hand, the concentration of heavy metals as Nickel also decreased by about 55 %, which confirms the efficiency of the used remedies. Also, application of these remedies had increased the total contents of organic carbon, nitrogen, phosphorus and potassium in the treated samples than those in untreated ones. The application of organic remediation of contaminated soils led to limited increase on EC and pH values this result confirms the importance of these organic remedies to reduce the harmful effects on the properties of remedied soil.

“…2-Naphthol is an organic pollutant presented in the environment as a result of dyestuffs manufactory, pharmaceutical production and some biogeochemical processes [23]. Because of its strong toxicity and low biodegradability, the removal of 2-naphthol is of great importance in water treatment.…”

A factorial experimental design was developed to describe the photocatalytic degradation of β-naphthol in a circulating photo-reactor using TiO 2 aqueous suspension. The main and interaction factors studied were the initial concentration of β-naphthol, TiO 2 dosage, pH and circulation flow. The parameters coded as X 1 , X 2 , X 3 and X 4 , consecutively, and were investigated at two levels (−1 and +1). The effects of individual variables and their interaction effects for dependent variables, namely, photocatalytic degradation efficiency (%) were determined. The experimental results and statistical analysis show that increasing in the initial concentration of β-naphthol decreases the photocatalytic degradation efficiency whereas the increase of TiO 2 dosage, pH and the circulation flow have a positive effect on the photocatalytic degradation. The interaction between TiO 2 dosage and circulation flow was the most influencing interaction. However, the interaction between TiO 2 dosage and pH was the least influencing interactions. The variance analysis (ANOVA) was applied and the statistic data showed adequate model.
