Abstract

Organic pollutants have negative impact on the human health and environment. Some organic pollutants are dangerous, such as Ametryn, it is toxic to human beings creating nausea, vomiting, diarrhea, muscle weakness, salivation and cancer. Besides, it creates irritation to the skin, eyes and respiratory tract. Tramadol hydrochloride may produce significant neurologic toxicity, including seizures, Lethargy, Agitation, Dizziness, Seizures, Confusion, Ataxia, Diplopia, coma and respiratory depression, in addition to mild tachycardia and hypertension. Dyes are toxic and can release compounds that are more toxic and even mutagenic, even at very low concentrations may significantly affect aquatic life when free in the environment will absorb sunlight preventing it to be used by photosynthetic organisms. Numerous researchers are looking for an effective method to solve this issue. Adsorption, using a modified kaolinite as an adsorbent, is useful method for the removal of water organic pollutants. Also heterogeneous photocatalysis, using a semiconductor as a catalyst loaded over Kaolinite, is apromising and saving method for the destruction of water organic pollutants. This method has been called the Advanced Oxidation Process (AOP) which is one of the techniques for water treatment. Zinc oxide (ZnO) is the most widely accepted photocatalyst because it is non-toxic, stable to photocorrosion, low cost and can potentially work using sunlight rather than artificial sources of light. This work aims at monitoring ametryn and tramadol hydrochloride in drinking and related raw water at Arab Republic of Egypt and removing tramadol hydrochloride, ametryn, methylene blue and malachite green from water using modified kaolinite and Kaolinite/ZnO nanocomposite as low cost treatment technique. The quantification and identification of ametryn and tramadol hydrochloride were explored using LC/MS/MS instrument and the analytical method used was in-house method based on (EPA, 536). The identification and quantification of malachite green and methylene blue dyes were explored using spectrophotometer. The study recorded the presence of ametryn and tramadol hydrochloride during (2018-2019) in different regions of Arab Republic of Egypt such as Sohag, Aswan, K. El Sheikh, El-Bhyra Governorates, AR Rahawi channel and Rosita river Nile branch, this is due to using tramadol hydrochloride as analgesic drug and ametryne as pesticides to control broadleaf weeds and annual grasses in sugarcane, bananas, maize and pineapple. Some trials were carried out to degrade and adsorb these organic Pollutants using modified kaolinites and kaolinite/ZnO nanocomposite. Around 81% - 85% of 8000µg/l malachite green, 90% - 98% of 10000µg/l methylene blue, 77% - 86% of 2000µg/l tramadol hydrochloride and 60% - 95% of 50µg/l ametryn were removed by K-HCl and K-H2SO4 respectively. Furthermore 85% of 8000µg/l malachite green, 98% of 10000µg/l methylene blue, 57% of 2000µg/l tramadol hydrochloride and 70% of 50µg/l ametryn were removed by kaolinite/ZnO nanocomposite, and this percentage was increased by increasing the time, and adsorbent dose, while its was decrease by increasing the concentration. On the other hand K-KOH had no effect in removing tramadol hydrochloride and ametryn, but it was effective in removing malachite green and methylene blue.
