Lampiran 1. Metode ekstraksi sodium alginat dari rumput laut.

Rumput laut kering

Perendaman dalam HCl 1% 1 jam (rumput laut: HCl 1: 30 b/v)

Pencucian dengan air bersih sampai pH netral

Ekstraksi dengan larutan Na2CO3 2% sebanyak 1:30 (w/v),

pada suhu 600C - 700C, selama 60 menit, digiling dan ekstraksi dilanjutkan selama 60 menit

Penyaringan hasil ekstraksi disaring dengan

vibrator 150- mesh

Pemucatan ditambahkan NaOCl 4% volume filtrat selama 30 menit

Pengendapan asam alginat filtrat di tambahkan HCl 10% sampai pH 2.8 3.2, endapan asam alginat dipisahkan dan dicuci bersih

Konversi menjadi natrium alginat dititrasi dengan Na2CO3 10% sampai pH 7

Pemisahan natrium alginat filtrat dituangkan sedikit demi sedikit ke dalam Isopropil alkohol (1:2 v/v)

sambil diaduk dan dibiarkan selama 30 menit

Pengeringan dan penggilingan serat alginat dikeringkan dibawah sinar matahari selama + 12 jam,

sampai kadar air 12%

digiling dengan ukuran 60 mesh

bubuk natrium alginat
