ABSTRAK
Loji rawatan kumbahan (STP) sedia ada khususnya di Malaysia tidak direka untuk menyingkirkan bahan farmaseutik yang tergolong dalam kategori bahan cemar baru muncul. Oleh kerana farmaseutik yang hadir dalam persekitaran akuatik ialah pada kepekatan yang sangat rendah iaitu dalam julat bahagian per bilion dan trilion, satu kaedah pengekstrakan dan analisis yang peka perlu dibangunkan. Dalam kajian ini, kaedah analisis berdasarkan pengekstrakan fasa pepejal (SPE) diikuti dengan kromatografi cecair-spektrometri jisim masa penerbangan (LC-TOF-MS) menggunakan mod pengionan secara semburan elektro positif telah berjaya dibangunkan untuk menentukan kehadiran sepuluh farmaseutik terpilih dalam air kumbahan dan air sungai. Farmaseutik yang dikaji termasuk acetaminophen, theophylline, caffeine, metoprolol, sulfamethoxazole,
carbamazepine, prednisolone, ketoprofen, norgestrel dan simvastatin. Kaedah SPE menggunakan langkah pengekstrakan tunggal yang menggunakan isi padu sampel yang rendah sebanyak 100 mL dan pelarut elusi yang minimum telah berjaya dicapai. Peratus perolehan semula untuk kesemua farmaseutik dalam sampel air sungai berada dalam julat 54-99% manakala bagi sampel efluen STP pula berada dalam julat 57-96%. Jangka masa analisis LC-TOF-MS termasuk masa imbangan adalah selama 25 min dengan menggunakan suntikan sampel 20 μL. Prosedur SPE bersama-sama dengan kaedah analisis yang telah dibangunkan menghasilkan had kuantifikasi (LOQ) dalam lingkungan 0.031-0.882 μg/L untuk sampel STP dan 0.030-0.926 μg/L untuk sampel air sungai.

ABSTRACT
Sewage treatment
plants (STPs) particularly in Malaysia are not designed to
eliminate pharmaceuticals which belong to the category of emerging
contaminants. Considering the levels of these contaminants could be incredibly
low which are in the range of parts per billion and trillion in the aquatic
environment, very sensitive analytical techniques and extraction methodologies
have to be developed. In this present work, an analytical method based on solid
phase extraction (SPE) followed by liquid
chromatography-time-of-flight mass spectrometry (LC-TOF-MS)
in positive electrospray ionisation mode was
successfully developed to determine the presence of ten selected
pharmaceuticals in aquatic environment. The compounds under study include
acetaminophen, theophylline, caffeine, metoprolol, sulfamethoxazole,
carbamazepine, prednisolone, ketoprofen, norgestrel and simvastatin. The SPE procedure
was successfully achieved with a single extraction step using a low sample
volume of 100 mL and minimum volume of eluting solvent. Percentage recovery for
all pharmaceuticals in river water samples were in the range of 54-99% while
for STP effluent samples were in the range of 57-96%. The
total run time inclusive of equilibration in LC-TOF-MS analysis
was 25 min with sample injection volume of 20 μL.
The application of the optimised SPE procedure
together with the instrumental analysis resulted in limit of quantification (LOQ)
of 0.031 - 0.882 μg/L and 0.030 - 0.926 μg/L in STP and river water samples, respectively.
