Properties of coir
According to TAPPI (1988), coconut fiber and organic matter can be re-used. The pH of coir is 5.5. quality
quantity of coconut fiber is not affected if the pH is lower. Coir has a number of properties and the
following chemical composition:
The C: N of 80: 1.
10-12% porosity.
Organic matter: 9.4 to 9.8%.
The total ash content: 3-6%.
Cellulose: 20-30%.
Lignin: 60-70%
Tannins: 8.0 to 8.5% (which are not hydrolyzed pyrocatechic-tannin).
EC (dS / m) 0.8.
N% 0.5.
P% 0.3.
K% 0.4.

. The cellulose molecules are unbranched chains, with
together to create a solid structure, high intensity stretch. Collection of molecules into the
micro fiber can be arranged along the vessel wall, a straight horizontal or primitive cell membranes. Molecules
cellulose are composed of several thousand units b - D - glucose connected by link b - 1.4 -
glucoside. Cotton is a natural fiber cellulose purest (90%); larch, cypress (coniferous)
approximately 50% cellulose, about 80% coconut fiber cellulose.
Cellulose does not dissolve in organic solvents, in the lye water and inorganic acids

II.4 / processing methods as adsorbent (VLHP)
a) Treatment of activated carbon to VLHP
Activated carbon is a form of carbon composed mainly of carbon, characteristic honeycomb structure
referendum. With this structure, the surface area of activated carbon is very large, reaching 600 - 1500m

depending on the quality of coal)
Activated carbon is mainly prepared by pyrolysis
carbon-containing raw materials at temperatures less than 1000

C.
Activated carbon is the adsorbent quarter and flexible, are used
widely for many purposes such as removing color, odor, taste not
desired and organic contaminants, inorganic wastewater
and industrial activity, recovered solvents, cleaning
air, in the air pollution control of industrial emissions
and engine emissions, in many cleaning chemicals, pharmaceuticals
products, food products and a variety of applications in the gas phase.
The examined material: coconut fiber, rice husk, bamboo, jute, bagasse
Sugarcane is composed mainly of cellulose (coir, jute, bagasse
cane) and semi-cellulose (hemicellulose, husk). Themselves on the material contained capillary system
Managing large size in the range 10 - 50 micron. Except husk material inorganic concentrations
(ash) quite large (12%), other materials have the advantages of low ash used as raw
materials made of activated carbon. Three materials were selected to study the husk, bamboo and coir.
[3]
Activated carbon prepared from rice husk is done in three methods: pyrolysis (chemical coal)
in anaerobic conditions, coal chemical and simultaneously activated with soda and phosphoric acid
Activated carbon made from coconut fiber to achieve adsorption on par with commercial coal
Outstanding when activated with phosphoric acid in easier conditions (low temperature,
short time, low levels of chemicals [3]
Pros: good adsorbent, simple manufacturing methods, inexpensive materials, the specific surface
large
Cons: only physical adsorption is the appropriate diameter hole diameter pad.
Activator complex conditions,
b) Modified Handling as VLHP
Denaturation process is the chemical used to process materials which contain molecular structure
A large number of functional groups that, in order to form new links, new functional groups or
the empty slot, ... can be used to adsorb some substances and heavy metals.
With the main component is about 80% cellulose, coir is a suitable material for
be modified to become a good adsorbent, the world and in some countries have
Scientific studies modified some materials are agricultural products such as coir, bagasse
sugarcane, rice husk ... adsorbent for environmental remediation. The research team at the Institute for Chemistry, Institute
science and technology India VLHP survey and made from bagasse treated with citric acid to
split type Cr (VI) in aqueous solution. The results obtained showed variations tinhbang bagasse citric acid

In Vietnam, there have been studies VLHP made from coir and husk with citric acid to
adsorption of toxic heavy metals such as Cu, Pb, Ni, Cd, As, Hg. These metals are related
directly to the GMO, cancer and serious impact on the environment [6]. The

Pros: simple method of implementation, can adsorb some heavy metals through

Cons: not high adsorption performance.
opinion
From the advantages of the modified method can be realized as a method modified
use appropriate methods for handling toxic heavy metals, which saves costs but still provide
high-performance processors. Most are in the process of textile dyeing wastewater treatment and metal concentrations

and highly complex.

Coco peat is an organic material and uses part of the coconut. Environment will not be harmed when using coco peat for planting.

Coco peat is excellent substrate for the growth of plant roots. And so, we can transplant directly coco peat in the past without any processing or other user agent.

Unlike the plant in the soil environment clean, coco peat to keep the air pressure high, even when the storm quite proud.

Although many coco peat air pressure than the storm quite proud of coco peat moisture but still much higher than the growth medium mixed with nutrients (except coconut puree acne).

Over time, coco peat will increase the capacity of the buffer zone to help crops withstand the lack of fertilizer and water in a short time.
