| description | Tropical peat soil after chemical modifica tion was found to be an effective coagulant for
clarification of some textile dyes from their aqueous solution. A thorough comparative study with
conve ntional coagulant had also been done. Results show that it can remove reactive, vat and disperse
dyes from their 50 mgIL aqueous solution. It was found that the removal for reactive blue 19 and
cibacron brilliant red was 99% and 97%, vat blue 14 and disperse red 72, 98% and 97% respectively.
Even though our study with 10% alum and PAC (Poly Aluminium Chloride) solution showed a 100%
removal of disperse and vat dyes, both of them showed a poor removal of two reactive dyes. Peat
coagulant had a wide pH working range, however its optimum pH range was from pH 3 to 5. On the
other hand, alum and PAC showed specific working pH of 5 for two reactive dyes, but they showed
wide pH working range for disperse and vat dyes. The mechanism for coagulation by peat coagulant
was proven as charge adsorption neutralisation process. The study with textile wastewater shows a
94% removal of colour and 98% removal of suspended solids by using peat coagulant. |
