Bu çalışmada, kalsiyum oksit (CaO) varlığında gezegen hareketli bilyalı değirmen kullanılarak teknik hegzaklorosiklohegzan’nın (t-HCH) mekanokimyasal parçalanma verimi araştırılmıştır. Kalıntı içeriğindeki t-HCH miktarı elektron dedektörlü gaz kromatografi (GC-µECD) ile analiz edilmiş ve 6 saat sonunda parçalanma verimi %99.7 olarak bulunmuştur. Pantaklorosiklohegzen, tetraklorobenzen, triklorobenzen, diklorobenzen ve monoklorobenzen gibi parçalanma ürünleri Headspace Gaz kromatografisi-kütle spektrometresi (GC-MS) ile tespit edilmiş ve temel parçalanma yolu önerilmiştir. Sonuçlar son ürünlerin amorf karbon ve suda çözünür klorür olduğunu göstermiştir. Çalışma CaO’nun t-HCH’nin parçalanmasında etkin olarak kullanılabileceğini göstermiştir.
