Abstract
Aktivasi bentonit dengan metode sederhana, ekonomis, ramah lingkungan, dan cepat dipelajari untuk menghasilkan kualitas bentonit teraktivasi asam yang baik dan berhasil dibuat dengan material bahan baku bentonit berasal dari Pacitan dan HCl. Analisa XRF menunjukkan bahwa terjadi penurunan kation Fe3+, Ca2+, Mn2+, Cu2+, dan Zn2+ dalam interlayer akibat adanya perlakuan dengan asam klorida, sehingga persentase Si4+, Al3+, Ti4+ dan K+ mengalami kenaikan. Analisa XRD menunjukkan bahwa kedua bahan baku bentonit memiliki komponen utama berupa montmorillonite. Luas permukaan spesifik mengalami peningkatan sebelum dan sesudah aktivasi. Untuk sampel dengan bentonit yang telah melalui proses pemisahan, peningkatan luas permukaan masing-masing sebesar 89,003 m2/g dan 441,946 m2/g. Material sebelum perlakuan dengan asam lebih pejal daripada material setelah perlakuan dengan asam diamati menggunakan SEM. Performa bleaching terbaik diraih pada sampel bentonit teraktivasi yang telah dipisahkan dengan perbandingan massa dan volume asam sebesar 10:30 dibandingkan dengan material komersial.

Bentonite activation in a simple, economical, environmentally friendly and quickly studied to produce good quality acid activated bentonite and it is successfully made with bentonite as raw material derived from Pacitan. XRF analysis shows that there is a decrease in cations Fe3+, Ca2+, Mn2+, Cu2+, dan Zn2+ in the interlayer due to treatment with HCl, so the percentage of Si4+, Al3+, Ti4+ and K+ has increased. XRD analysis shows that the two raw materials of bentonite have a major component in the form of montmorillonite. Specific surface area has increased, before and after activation. For samples with bentonite through by separation process, the increase in surface area is 89,003 m2/g and 441,946 m2/g, respectively. Material before treatment with acid is more solid than material after treatment with acid was observed using SEM. The best bleaching performance was achieved in activated bentonite samples which had been separated by a mass ratio and acid volume of 10:30 compared to commercial material.
