Buangan air sisa dari industri tekstil perlu dirawat sebelum dilepaskan ke dalam alam sekitar kerana air kumbahan ini mengandungi kandungan toksik yang tinggi dan boleh membawa kepada pencemaran air yang serius. Model rawatan air sisa kos rendah yang mesra alam, telah dihasilkan untuk menyelesaikan masalah ini. Filem NR-b-PVP/Ag yang dihasilkan daripada campuran getah asli dengan polyvinylpyrrolidone (PVP) yang digabungkan dengan zarah perak dilapisi di atas permukaan kaca untuk menurunkan pewarna metil oren (MO) melalui cara fotodegradasi pada pH 7. Proses fotodegradasi dijalankan di bawah cahaya matahari selama 2 jam dan 2 mL sampel diambil untuk menganalisis kapasiti penyerapan pada panjang gelombang puncak untuk MO, 463 nm, melalui Spectrophotometer UV-Vis pada setiap 20 minit. Tesis ini menekankan kesan persediaan kaedah kaca, kesan kepekatan perak nitrat (AgNO3) dan kesan kelajuan aliran larutan MO. Degradasi tertinggi untuk 5 liter larutan MO yang dicapai dalam kajian ini adalah 86.6% apabila teknik Gabungan Kaca, 0.3 kepekatan AgNO3 dan 400 mL/min digunakan.

Effluent of wastewater from textile industries need to be treated before discharge into environment as this wastewater contains high toxicity which can lead to serious water pollution. Environmentally friendly, low cost dye wastewater treatment model have been produced in order to solve this issue. NR-b-PVP/Ag film prepared from blends of natural rubber latex with polyvinylpyrrolidone incorporated with silver particle was coated onto the surface of the glass to degrade methyl orange (MO) dye via photodegradation at neutral pH. The process of photodegradation was conducted under the sunlight for 2 hours and 2 mL of sample was taken to analyse the absorbance capacity at peak wavelength of MO, 463 nm, via UV-Vis Spectrophotometer for every 20 minutes. This thesis emphasizes the effect of method setup of the glass, effect of silver nitrate (AgNO3) concentration and effect of flowrate of the MO solution. The highest degradation of 5 Liters of MO solution achieved in this study was 86.6% when Glass Combine method, 0.3 g/mol of AgNO3 with 400 mL/min was applied.
